TODO:
- let choose_best_mode take aspect into account
- set palette from mpi->palette or mpi->plane[1]
- let OSD draw in black bars - need some OSD changes
- make faster OSD black bars clear - need some OSD changes
- Make nicer CONFIG parsing
- change video mode logical width to match img->stride[0] - for HW only
