Two new lcd/multi screen api convinience functions: draw_viewport(), fill_viewport().
They work as the drawrect/fillrect pendants but work on a viewport basis; pass NULL to draw the current viewport (the one set with set_viewport()). In conjunction with action_get_touchscreen_press_in_vp() it should be less of a pain to draw buttons and get presses on them. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28239 a1c6a512-1295-4272-9138-f99709370657
