[FEATURE] Smoother mode switch

[arncht]

hi,

is it possible to make blackout during the mode switch? how i see, it detects more things automatically compared to the original ossc (eg phase), but the "jumping" screen is not nice during a demoscene demo. many demos has multiple mode switching between the scenes within the same run.

here an intro, this example continuously jumps between the vga and the mode-x modes (it is an old datapath capture): https://www.youtube.com/watch?v=KPYZHeroeNU

alternatively would it be possible to store the previous mode switch result (if it detects something over the mode)? i use various pcs/video cards with slightly different outputs, if the mode used once on this card, just reload the previously used settings eg the phase.

thx, arncht
