SVN commit 520822 by mwiesweg:

digikam from trunk: DImg

Handle pre- and demultiplication:
 - add explicit comment that DImg stores non-premultiplied data
 - add pre- and demultiplication support to DImg
 - add pre- and demultiplication support to DColorComposer

Reduce use of uint in DImg:
 - be consistent and use signed int for all region specifications,
   these are checked and normalized, so negative values are all right
 - for the remaining public uses of uint, it is either clear that the caller
   must provide correct values (constructor, putImage), or
   wrong values will be caught anyway (getsetPixelColor)
 - fix warnings in dimgscale.cpp

BitBlt:
 - split bitBlend again in bitBlt and bitBlend, but share normalization code
 - allow to specifiy a DColorComposer::MultiplicationFlag in bitBlendImage
 - fix bug in bitBlend loop
