If you use the X-target then everything is unaccelerated, because the
X-target emulates a framebuffer.
Try the Xlib-target. You can force each ggi program to use a certain
target by setting the environment variable GGI_DISPLAY="<target>"
All operations are accelerated Xlib, only blitting is slower than X.
Detailed information about environment variables and targets can be found
at
libggi/doc/env.txt, libggi/doc/targets.txt and on our GGI documatation
