ok,
Excuse my ignorance, but I am still a bit confused. The line of code I
referred to earlier
(pPixmap = kaaGetOffscreenPixmap (pDrawable, &xoff, &yoff)) &&
in kaa.c seems to always return NULL and therefore will never call the
PrepareSolid as well as the Solid functions defined by my driver. Or
is this a bug in the init of my driver not filling out the structures
properly?
