Would it support RGB color shifting?  For example, I'd like to be
able to apply color offsets to an in-memory pixmap to simulate
time of day (twilight vs. noon) and seasonal differences (orange
in fall vs. green in spring), without having to create/load a
different set of pixmaps for each possibility (e.g.
pinetree_autumn_midday.png).  Here's a good presentation of where
I'm coming from (sorry, it's sort of graphics-intensive):
