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.
