Why can't we just let the client (Stefan) draw to the offscreen part
of the framebuffer?  I wrote a little demo (with minor changes to the fbdev
code) program that allowed me to draw offscreen (outside of the virtual area)
and then use ggiCopyBox to blit it to the viewable (virtual/pannable) area when
needed. What am I missing here?

fntPrintChar(rootvis, font, 'a', xpos, ypos, pixs);  /* offscreen */

ggiGetc(rootvis); /* nothing is viewable */
ggiCopyBox(rootvis, xpos + dim.dx, ypos + dim.dy , dim.width, dim.height, 100 + 
dim.dx,100 + dim.dy); /*  all of a sudden an 'a' appears  */
