2431bf1b20 QPixelFormat: don't inherit it
Instead of abusing inheritance to provide convenience constructors,
use simple inline constructor functions. The name got a lower-case
q to indicate a free function. The usual fromXYZ() static methods
were deemed not fitting in this case in the initial round of review,
since they implied some kind of conversion while these functions are
simply constructors of formsts, which contain no data.

This also solves the problem that some of these ctors could have been
called with just one argument and were therefore candidates for hidden
QPixelFormat temporary injection.

QPixelFormatRgb was renamed to qPixelFormatRgba to explain the third
argument at the call site better.

There seem to be no users of this class in qt5.git at this time.

d8dc664b94 Ensure valid data after QImage::invertPixels
QImage::invertPixels may produce invalid data after inversions of
images with premultiplied alpha, because the inverted colors will be
larger than the alpha.

This patch converts any image with a premultiplied alpha channel to
ARGB32 before inverting the pixels, and then back to the original
format after the inversion.

Support is added for correct inversion of RGBA8888 and RGB30 formats.

70dd563046 Correct QImage::fill(uint) on RGBA8888 formats
QImage::fill(uint) was incorrectly performing ARGB->RGBA conversion when
called on RGBA8888 formated images.

This patch moves the color conversion to QImage::fill(QColor) where it
belongs so that fill(uint) can behave consistent with documentation and
how it treats other formats.

The fill(uint) method had no automated tests, and this patch adds one.

[ChangeLog][QtGui][QImage] QImage::fill(uint) now fills the given pixel
value unconverted when used on RGBA8888 image, making it consistent with
the documentation and treatment of all other image formats.

78f6d144d6 Serialize QPicture using the latest QDataStream version.
The QDataStream version with which QPicture was previously serialized
with was hard-coded to 11 (Qt 4.5). This prevents features of
serializable types used by QPicture from being serialized if they
were added after Qt 4.5; namely features of QFont like
HintingPreference.

[ChangeLog][QtGui][QPicture] QPicture now serializes its data properly
by also accounting for QDataStream versions greater than Qt 4.5.

c4d8734c50 Avoid out of bounds memory reads when scaling images
The calculation of the width/height required for the
scaling algorithm was prone to floating point rounding
issues, where the lower value got rounded down, the higher
one rounded up. This could lead to a situation where we
iterated over one more line/pixel in the line than we have
in the source image.

Correct this by passing the dimension of the source image into
the function and bounds checking the values before iterating.

ff70c39ebc Ensure QImage::pixel() on RGB32 images returns valid QRgb values
Currently QImage::pixel() returns the raw underlying pixel values for
RGB32. For all other pixel formats the returned value is either valid
ARGB32 or ARGB32PM.

This patch masks the undefined alpha field in RGB32 so that the return
value is well defined QRgb. It also fixes one test that relied on the
previous behavior.

0226795cf3 Round evenly in INV_PREMUL
Currently INV_PREMUL rounds strictly down. While PREMUL rounds evenly.

This patch adds 0x8000 to the intermediate results in INV_PREMUL before
right shifting, thereby achieving even rounding.

The rounding also makes PREMUL(INV_PREMUL()) into an identify operation,
which means we can safely convert ARGB32PM to ARGB32 and back without
ever losing color details. A test is added to verify this.

733430636d Fixed crashes when using QImage in combination with QCoreApplication.
As long as fonts weren't used we supported using QImage in combination
with QCoreApplication in 4.x, and there's no reason we can't continue
doing so.

62d25e4d4f Fixed QPixmapCache associating path with wrong QPixmap.
QPixmap::load() would not detach, so multiple paths could get associated
with the same QPixmap, causing the wrong pixmap to be shown.

af84313c62 Fixed crash in image reader when reading certain BMP files.
If the high bit in a mask is set, for instance if the mask is
0xff000000, and we shift it to the right by 24 positions, since the mask
was not declared as unsigned we ended up with a mask value of
0xffffffff. We then add 1 to this value and divide by the result,
causing a division by zero crash.

The masks need to be declared unsigned to prevent sign bit extension
when shifting right.

a9458a1755 Clean up logical dpi for QImage.
Revert to the pre highdpi-patch behaviour.

Before, both physical and logical DPI would be based
on the dpmx/dpmy variables, which could be changed
with setDotsPerMeter(). The highdpi patch introduced
separate ldpmx/ldpmy variables, which were not
changed by setDotsPerMeter().

This broke when loading images: setDotsPerMeter
would be called but the logical dpi would not change.

Remove ldpmx/ldpmy. Keep scaling the physical dpi
by the devicePixelRatio, which will be set to 1 by
default.
