vt_vga: Clip the draw area to never draw offscreen

This fixes a bug when two windows use different fonts, but a longer-term
solution is required. The dirty area should be stored as pixels, not
character cells, because such coordinates don't have the same meaning in
all windows, when using different fonts.
