Qt 5.13.2 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 5.13.0 through 5.13.1.
For more details, refer to the online documentation included in this
distribution. The documentation is also available online:
https://doc.qt.io/qt-5/index.html
The Qt version 5.13 series is binary compatible with the 5.12.x series.
Applications compiled for 5.12 will continue to run with 5.13.

****************************************************************************
* QtCore *
****************************************************************************
- Fixed a bug that made qErrnoWarning() say there was no error when
generating the error message.
- QBitArray:
* Fixed two bugs that caused QBitArrays created using fromBits() not to
compare equal to the equivalent QBitArray created using other methods
if the size was zero or not a multiple of 4. If the size modulus 8 was
5, 6, or 7, the data was actually incorrect.
- QCryptographicHash:
* Fixed a bug that caused the SHA-3 and Keccak algorithms to crash if
passed 256 MB of data or more.
- QObject:
* Fixed a resource leak caused by a race condition if multiple QObjects
were created at the same time, for the first time in an application,
from multiple threads (implies threads not started with QThread).
****************************************************************************
* QtGui *
****************************************************************************

* [QTBUG-69546] Fixed a crash bug in
QTextDocument::clearUndoRedoStacks(QTextDocument::UndoStack).

- sqlite:
* Updated to v3.29.0

- Linux:
* [QTBUG-61916] Added an environment variable
QT_QPA_PRESERVE_CONSOLE_STATE that can be used to prevent Qt from
altering the tty screen and cursor settings when running with
platforms like linuxfb and eglfs.
- Android:
* [QTBUG-76036] Fixed an issue where menus would not work on 64 bit
builds.

CHANGES BETWEEN 2.10.0 and 2.10.1
I. IMPORTANT BUG FIXES
- The bytecode hinting of OpenType variation fonts was flawed, since
the data in the `CVAR' table wasn't correctly applied.
II. MISCELLANEOUS
- Auto-hinter support for Mongolian.
- For distribution, `.tar.bz2' packages are replaced with `.tar.xz'
bundles.
- The handling of the default character in PCF fonts as introduced
in version 2.10.0 was partially broken, causing premature abortion
of charmap iteration for many fonts.
- If `FT_Set_Named_Instance' was called with the same arguments
twice in a row, the function returned an incorrect error code the
second time.
- Direct rendering using FT_RASTER_FLAG_DIRECT crashed (bug
introduced in version 2.10.0).
- Increased precision while computing OpenType font variation
instances.
- The flattening algorithm of cubic Bezier curves was slightly
changed to make it faster. This can cause very subtle rendering
changes, which aren't noticeable by the eye, however.
- The auto-hinter now disables hinting if there are blue zones
defined for a `style' (i.e., a certain combination of a script and
its related typographic features) but the font doesn't contain any
characters needed to set up at least one blue zone.
- The `ftmulti' demo program now supports multiple hidden axes with
the same name tag.
- `ftview', `ftstring', and `ftgrid' got a `-k' command line option
to emulate a sequence of keystrokes at start-up.
- `ftview', `ftstring', and `ftgrid' now support screen dumping to a
PNG file.
- The bytecode debugger, `ttdebug', now supports variation TrueType
fonts; a variation font instance can be selected with the new `-d'
command line option.
======================================================================
CHANGES BETWEEN 2.9.1 and 2.10.0
I. IMPORTANT CHANGES
- A bunch of new functions has been added to access and process
COLR/CPAL data of OpenType fonts with color-layered glyphs.
FT_Palette_Data_Get
Retrieve color palette data.
FT_Palette_Select
Select and activate a color palette for color-layered
glyphs.
FT_Palette_Set_Foreground_Color
Set text foreground color for palette index 0xFFFF.
FT_Get_Color_Glyph_Layer
Get color layers for a given glyph (using an interator
object).
FT_Bitmap_Blend
Blend one bitmap onto another with a given color.
- An experimental feature is the new behaviour of the
`FT_LOAD_COLOR' load flag for color-layered glyphs: Internally
it sets a flag so that if `FT_Render_Glyph' is called with
`FT_RENDER_MODE_NORMAL' (or `FT_Load_Glyph' with
`FT_LOAD_RENDER'), a default blending of the color glyph layers
will happen automatically for convenience.
- As a GSoC 2018 project, Nikhil Ramakrishnan completely
overhauled and modernized the API reference.
II. MISCELLANEOUS
- The logic for computing the global ascender, descender, and
height of OpenType fonts has been slightly adjusted for
consistency.
. If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection'
field) in the `OS/2' table is set, use the `sTypo' fields in
`OS/2' unconditionally.
. Otherwise use the metrics data from the `hhea' table (if not
zero).
. Otherwise use the `sTypo' fields from the `OS/2' table (if not
zero).
. Otherwise use the `usWin' data from the `OS/2' table as a last
resort.
Variable fonts will apply the `MVAR' deltas to whichever metrics
were picked.
- `TT_Set_MM_Blend' could fail if call repeatedly with the same
arguments.
- The precision of handling deltas in Variation Fonts has been
increased. The problem did only show up with multidimensional
designspaces.
- New function `FT_Library_SetLcdGeometry' to set up the geometry
of LCD subpixels.
- FreeType now uses the `defaultChar' property of PCF fonts to set
the glyph for the undefined character at glyph index 0 (as
FreeType already does for all other supported font formats). As
a consequence, the order of glyphs of a PCF font if accessed
with FreeType can be different now compared to previous
versions.
This change doesn't affect PCF font access with cmaps.
- `FT_Select_Charmap' has been changed to allow parameter value
`FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT
formats to access built-in cmaps that don't have a predefined
`FT_Encoding' value.
- A previously reserved field in the `FT_GlyphSlotRec' structure
now holds the glyph index.
- On Win32 platforms, the use of `_DLL' to build the library has
been replaced with `DLL_EXPORT' and `DLL_IMPORT'.
- The usual round of fuzzer bug fixes to better reject malformed
fonts.
- `FT_Outline_New_Internal' and `FT_Outline_Done_Internal' have
been removed. These two functions were public by oversight only
and were never documented.
- A new function `FT_Error_String' returns descriptions of error
codes if configuration macro FT_CONFIG_OPTION_ERROR_STRINGS is
defined.
- `FT_Set_MM_WeightVector' and `FT_Get_MM_WeightVector' are new
functions limited to Adobe MultiMaster fonts to directly set and
get the weight vector.
- Support for Position Independent Code as needed by systems that
prohibit automatic address fixups, such as BREW, has been
removed. [Compilation with modern compilers that use flags like
`-fPIC' or `-fPIE' is not affected.]
- The `ftdump' demo program has new options `-c' and `-C' to
display charmaps in compact and detailed format, respectively.
Option `-V' has been removed.
- The `ftview', `ftstring', and `ftgrid' demo programs use a new
command line option `-d' to specify the program window's width,
height, and color depth.
- The `ftview' demo program now displays red boxes for zero-width
glyphs.
- `ftglyph' has limited support to display fonts with
color-layered glyphs. This will be improved later on.
- `ftgrid' can now display bitmap fonts also.
- The `ttdebug' demo program has a new option `-f' to select a
member of a TrueType collection (TTC).
- Other various improvements to the demo programs.

* Error Enumerations
*

* How to handle errors and error strings.
*
* @description:
* The header file `fterrors.h` (which is automatically included by
* `freetype.h` defines the handling of FreeType's enumeration
* constants. It can also be used to generate error message strings
* with a small macro trick explained below.
*
* **Error Formats**
*
* The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
* defined in `ftoption.h` in order to make the higher byte indicate the
* module where the error has happened (this is not compatible with
* standard builds of FreeType~2, however). See the file `ftmoderr.h`
* for more details.
*
* **Error Message Strings**
*
* Error definitions are set up with special macros that allow client
* applications to build a table of error message strings. The strings
* are not included in a normal build of FreeType~2 to save space (most
* client applications do not use them).
*
* To do so, you have to define the following macros before including
* this file.
*
* ```
* FT_ERROR_START_LIST
* ```
*
* This macro is called before anything else to define the start of the
* error list. It is followed by several `FT_ERROR_DEF` calls.
*
* ```
* FT_ERROR_DEF( e, v, s )
* ```
*
* This macro is called to define one single error. 'e' is the error
* code identifier (e.g., `Invalid_Argument`), 'v' is the error's
* numerical value, and 's' is the corresponding error string.
*
* ```
* FT_ERROR_END_LIST
* ```
*
* This macro ends the list.
*
* Additionally, you have to undefine `FTERRORS_H_` before #including
* this file.
*
* Here is a simple example.
*
* ```
* #undef FTERRORS_H_
* #define FT_ERRORDEF( e, v, s ) { e, s },
* #define FT_ERROR_START_LIST {
* #define FT_ERROR_END_LIST { 0, NULL } };
*
* const struct
* {
* int err_code;
* const char* err_msg;
* } ft_errors[] =
*
* #include FT_ERRORS_H
* ```
*
* An alternative to using an array is a switch statement.
*
* ```
* #undef FTERRORS_H_
* #define FT_ERROR_START_LIST switch ( error_code ) {
* #define FT_ERRORDEF( e, v, s ) case v: return s;
* #define FT_ERROR_END_LIST }
* ```
*
* If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
* be replaced with `FT_ERROR_BASE(error_code)` in the last example.
*/

/* In previous FreeType versions we used `__FTERRORS_H__'. However, */
/* In previous FreeType versions we used `__FTERRORS_H__`. However, */

* @description:
* Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
* `ftoption.h', which enables patented ClearType-style rendering,
* the LCD-optimized glyph bitmaps should be filtered to reduce color
* fringes inherent to this technology. The default FreeType LCD
* rendering uses different technology, and API described below,
* although available, does nothing.
* FreeType provides two alternative subpixel rendering technologies.
* Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
* `ftoption.h` file, this enables patented ClearType-style rendering.
* Otherwise, Harmony LCD rendering is enabled. These technologies are
* controlled differently and API described below, although always
* available, performs its function when appropriate method is enabled
* and does nothing otherwise.
*
* ClearType-style LCD rendering exploits the color-striped structure of
* LCD pixels, increasing the available resolution in the direction of
* the stripe (usually horizontal RGB) by a factor of~3. Since these
* subpixels are color pixels, using them unfiltered creates severe
* color fringes. Use the @FT_Library_SetLcdFilter API to specify a
* low-pass filter, which is then applied to subpixel-rendered bitmaps
* generated through @FT_Render_Glyph. The filter sacrifices some of
* the higher resolution to reduce color fringes, making the glyph image
* slightly blurrier. Positional improvements will remain.
* the stripe (usually horizontal RGB) by a factor of~3. Using the
* subpixels coverages unfiltered can create severe color fringes
* especially when rendering thin features. Indeed, to produce
* black-on-white text, the nearby color subpixels must be dimmed
* equally.
*
* A filter should have two properties:
* A good 5-tap FIR filter should be applied to subpixel coverages
* regardless of pixel boundaries and should have these properties:
*
* 1) It should be normalized, meaning the sum of the 5~components
* should be 256 (0x100). It is possible to go above or under this
* target sum, however: going under means tossing out contrast, going
* over means invoking clamping and thereby non-linearities that
* increase contrast somewhat at the expense of greater distortion
* and color-fringing. Contrast is better enhanced through stem
* darkening.
* 1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
* any shifts in appearance.
*
* 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
* where a~+ b~=~c. It distributes the computed coverage for one
* subpixel to all subpixels equally, sacrificing some won resolution
* but drastically reducing color-fringing. Positioning improvements
* remain! Note that color-fringing can only really be minimized
* when using a color-balanced filter and alpha-blending the glyph
* onto a surface in linear space; see @FT_Render_Glyph.
* 2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
* fringes by distributing the computed coverage for one subpixel to
* all subpixels equally.
*
* Regarding the form, a filter can be a `boxy' filter or a `beveled'
* filter. Boxy filters are sharper but are less forgiving of non-ideal
* gamma curves of a screen (viewing angles!), beveled filters are
* fuzzier but more tolerant.
* 3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
* overall brightness.
*
* Examples:
* Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
* forgiving of non-ideal gamma curves of a screen (and viewing angles),
* beveled filters are fuzzier but more tolerant.
*
* - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
* normalized.
* Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
* API to specify a low-pass filter, which is then applied to
* subpixel-rendered bitmaps generated through @FT_Render_Glyph.
*
* - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
* normalized.
* Harmony LCD rendering is suitable to panels with any regular subpixel
* structure, not just monitors with 3 color striped subpixels, as long
* as the color subpixels have fixed positions relative to the pixel
* center. In this case, each color channel is then rendered separately
* after shifting the outline opposite to the subpixel shift so that the
* coverage maps are aligned. This method is immune to color fringes
* because the shifts do not change integral coverage.
*
* - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
* balanced.
* The subpixel geometry must be specified by xy-coordinates for each
* subpixel. By convention they may come in the RGB order: {{-1/3, 0},
* {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
* {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
*
* - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
* balanced.
* Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
* If one follows the RGB order convention, the same order applies to the
* resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps. Note,
* however, that the coordinate frame for the latter must be rotated
* clockwise. Harmony with default LCD geometry is equivalent to
* ClearType with light filter.
*
* - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
* balanced.
* As a result of ClearType filtering or Harmony rendering, the
* dimensions of LCD bitmaps can be either wider or taller than the
* dimensions of the corresponding outline with regard to the pixel grid.
* For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to
* the left, and 2~subpixels to the right. The bitmap offset values are
* adjusted accordingly, so clients shouldn't need to modify their layout
* and glyph positioning code when enabling the filter.
*
* - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
* balanced.
* The ClearType and Harmony rendering is applicable to glyph bitmaps
* rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
* @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
* is specified. This API does not control @FT_Outline_Render and
* @FT_Outline_Get_Bitmap.
*
* The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
* @FT_Load_Glyph, and @FT_Load_Char. It does _not_ affect the output
* of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
*
* If this feature is activated, the dimensions of LCD glyph bitmaps are
* either wider or taller than the dimensions of the corresponding
* outline with regard to the pixel grid. For example, for
* @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
* 3~subpixels to the right. The bitmap offset values are adjusted
* accordingly, so clients shouldn't need to modify their layout and
* glyph positioning code when enabling the filter.
*
* It is important to understand that linear alpha blending and gamma
* correction is critical for correctly rendering glyphs onto surfaces
* without artifacts and even more critical when subpixel rendering is
* involved.
*
* Each of the 3~alpha values (subpixels) is independently used to blend
* one color channel. That is, red alpha blends the red channel of the
* text color with the red channel of the background pixel. The
* distribution of density values by the color-balanced filter assumes
* alpha blending is done in linear space; only then color artifacts
* cancel out.
* The described algorithms can completely remove color artefacts when
* combined with gamma-corrected alpha blending in linear space. Each of
* the 3~alpha values (subpixels) must by independently used to blend one
* color channel. That is, red alpha blends the red channel of the text
* color with the red channel of the background pixel.
