fee16baca1 Another fix of cosmetic QPainter::drawPolyline()

any pixels even if not clipped by the floating-point clip
routine. Make sure the starting point for the next line is still
updated correctly for any significant segment lengths.

5551295028 Fix repremultiply from RGB64 to RGB30
Just like from RGB32 to RGB30 we must also repremultiply when converting
from RGB64 because the alpha channel loses more precision than the other
color channels.

Since this is not approximated accurately in the simple blending
functions and the functions are no longer needed now the main render
engine supports higher accuracy, the simple blending routines for RGB30
have been removed.

d5c6335ff3 Fix rasterization errors in aliased cosmetic drawPolyLine
If a cosmetic polyline contained a 1-pixel segment, the next segment
would be drawn with wrong starting point.

The original fix for QTBUG-26156 had some unwanted side effects
(QTBUG-31579 and now QTBUG-42398). It tried to skip start-point update
if stroke() did not actually draw anything (because the segment was
too small). However, to determine that, it tested for a change in
lastPixel. But that was not failsafe; in some cases (1-pixel segment),
lastPixel could be unchanged even though the segment had been
drawn. With this change, we instead test directly whether stroke()
skipped the segment or not.

In incremental follow-ups, we can then selectively either remove, or
port, the pieces that are dead code.

d056618d68 Make sure widget is polished before checking its font
QWidget is polished when show() is called, so unless you do this
first, QWidget::font() will return a default constructed QFont,
and not necessarily the default specified in the platform theme.
Comparing this to QPainter::font() later, which has been resolved
against the platform theme font, and not the default constructed
font, you can get a mismatch and a false test failure. This
happened on Android.

ae0ddb8c72 were all offset by one
composition mode because of a duplicate entry in the array. The

Most users will probably not have experienced this since any of

1aede2d7fc QPainter on QBitmap: make setBrush(NoBrush) work as expected.
It had no effect because of an explicit check for NoBrush.
However the default in QBitmap is (unfortunately) QBrush(color0), rather
than NoBrush, so the brush must be updated when calling setBrush(NoBrush).

I suppose the real issue is that lastBrush is default-constructed in
QRasterPaintEngine, rather than starting with the brush from QPainter,
which is QBrush(color0) for the case of the bitmap. But no reason to
special case NoBrush here anyway.

f4ebb06189 Remove Q_PACKED from structures that do not need to be packed
These structures do not need to be packed. With some compilers, Q_PACKED
was defined to be empty, which means that the code was working fine
without packing. Or there were some lingering problems on those
platforms (MSVC) and we're now exposing them in all platforms.

Actually, it shouldn't be a problem anywhere. QCharAttributes, quint24
and QFontEngineQPA::Glyph have only char/uchar members, so they're
packed already (they have alignof == 1). The only platform where that
wasn't true was ARM OABI, which we don't support anymore.

QFontEngineQPA::Header seems to always come from a QByteArray, so it
doesn't neeed to be packed either. However, just to be sure, I'm
inserting a check for alignment.

And QFontEngineQPA::Block isn't used anywhere.

52619ae778 Fixed invalid memory read in SSSE3 image blending code.
We need to do bounds comparison on the actual offset we're going to use
with _mm_load_si128 to read 16 bytes from memory (even though we won't
use the trailing bytes in the end).

07ea3cf0b3 qpa: Fix rendering issue in blitter engine (negative scaling factors)
A 180° rotation results in a TxScale QTransform with negative scaling
factors (x=-1.0 y=-1.0). This is not properly handled by blitter paint
engine yet, so use software rendering fallback in this case.

This rendering issue can be seen when using "-webkit-transform" CSS
property in WebKit with DirectFB QPA platform.

b213d5bfa3 Make QPen default to 1-width non-cosmetic.
Use the Qt4CompatiblePainting render hint when painting with QPainter to
treat default constructed QPens as cosmetic still.

The NonCosmeticDefaultPen render hint gets documented as obsolete, since
it was in any case not respected by the raster nor OpenGL paint engine.

7b8e10ddd0 Fixed inconsistent QPainter fill rules for aliased painting.
Qt 5 is the time to get rid of all the old inconsistencies in the raster
paint engine caused by trying to preserve the old X11 based
coordinate system where (0, 0) is in the center of the top-left pixel
instead of the upper left corner of said pixel. However, this was only
adhered for line drawing and path / rect filling, and not for image or
pixmap drawing and not at all when doing antialiased painting. By
defining the antialiased coordinate system as being the right one and
letting the aliased fill rules follow from that we finally end up with
some consistent behavior that doesn't lead to surprises and workarounds
in application code.

It is still possible for applications to get the old behavior by
setting the QPainter::Qt4CompatiblePainting render hint. This should
make porting easier for the few cases where an application relies on the
aliased fill rules we used to have in Qt 4.

This case has typically required specific work-arounds in other
