rockbox/apps/screen_access.c
Thomas Martitz 8a0152bd4a 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.
