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
value is well defined QRgb. It also fixes one test that relied on the
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.

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.

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.

The icon engine behind icons that are loaded from QIcon::fromTheme does
not scale any pixmaps that it returns. When using an icon theme with an
incomplete set of icons (for example, only a "128x128" folder),
QIcon::pixmap will always return 128x128 pixmaps even if you ask for
one of size 22x22.
This is contrary to the QIcon::pixmap documentation that says "The
pixmap might be smaller than requested, but never larger."
This patch uses the same code that is in the main QIcon class in the
PixmapEntry QIconLoaderEngineEntry to scale pixmaps if they are too big.
