Gamma-corrected blending in Qt5

[Dmitry Kazakov]

Hi, Rafael!

I think that handling ICC profiles when loading JPEG, PNG images by QImage
is really a must for Qt, if it doesn't handle ICC tag, then the result
might look wrong. But the painting code, as Boud already said, is too
specialized to go into Qt :)
