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.

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.

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 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.

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

previous behavior.

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.
