Changed to use panel plane tl and tr to center modes smaller then panel size.
The code is under "<hash>ifdef USE_PANEL_CENTER", as it is buggy, and regardless of value set to right and bottom, it will crop from 0 to mode-width/mode-height, and then display a lot of screen artifacts, due to improper programming. Either way, the CRT in clone mode will display correctly.
