Ir would be possible to add the terminal flag TERM_VIDEO_CAPABLE and
also write video part of module between #ifdef WITH_VIDEO and so compile
twice:
with video and without. Cons: last control for terminal rendering is on the
terminal driver, so even if they use some common functions like font
rendering there is
a risk that the terminals will be different with different video driver -
bad thing and in this way we must also have virtual screen support

We could do like terminal support, but separate
