: hehehe this is cool :-)
: So we might need the "alpha" part in the colormap of the framebuffer
: after all ?
:
Possibly for non-constant alpha blending. My demo shows constant
(per image or window) blending.
: but is there a update problem with the bottom window ?
: And how do you update generaly , you will always have to redraw the
: place
: where the window was (all windows in the place) and where it goes, bit
: different
: than the normal window clipping.
Actually the clipping can remain exactly the same, but, as explained
in my last email, drawing must occur multiple times for each overlapped
translucency...

Greg
