OK, can something be done about a generic interface for producing this
"combined mode" image? Something like

void GenerateCombinedImage(const Image& left, const Image& right,
const Rectangle& rectToProcess, const Params& params, Image& dest);

where left, right and dest provide some way to get at raw RGBA data,
width and pitch info, rectToProcess is the rectangle which has to be
rebuilt in dest, and Params contains e.g. the alpha for the current
"blend" mode, a mode identifier (e.g. blend/overlay with color/border
with color), overlay color etc.
