Re: clipping

BTW, do we really need clipping in fb_ops.fb_{fillrect,copyarea,imageblit}()?

Personally, I don't think we need clipping.  I tried removing it before
(circa linux-2.5.30+), but the console segfaults whenever I decrease
var->yres_virtual.  I haven't tried this again with the newest
framebuffer framework though.

Any definitive answer on this?

What happens if you resize the VT to such a large size that columns*fontwidth >
xres_virtual or rows*fontheight > yres_virtual? I guess clipping prevents a
crash there?

Correct. Actually fbcon_resize checks to make sure the user doesn't do 
something stupid like this. So we might not needed. Hm.
