        src/sys/arch/hppa/dev: gftfb.c

Log Message:
For some reason the drawing engine occasionally scribbles past the right
boundary when filling rectangles, especially annoying when we draw whitespaces
As a workaround we draw all rectangles less than 50 pixels wide by drawing
a 50 pixel rectangle into off-screen memory to the right of the visible fb and
then copy the portion we want. Keeps track of the colour and size of the
off-screen rectangle so we can avoid redrawing it whenever possible.
