GrReparentWindow mapping bug in demo2 app when wm running (temp fixed)
blit slow when moving windows in portrait mode
down portrait mode is not correct

add offscreen pixmap rotates when portrait changes (remove assert in GdBlit)
remove FIXME kluge in fb.c mapmem, fix offscreen rotation orientation for blits
add subdrivers above driver level for x11
add portrait switch layer above driver so it works with X11
any offscreen blit code will fail when in portrait mode

put back in DrawArea driver in GdArea
