I think I see something.
In srvfunc.c I notice several drawing functions: GrCreateFont, GrLoadImageFromFile
actually draws to the &scrdev and not to the pixmap. Is this correct? Am I following this correctly?
It appeard to me that there is something happening to the actual framebuffer while I'm writing to
the pixmap and I think I getting closer.
