Hi,

this is in the convert/ folder, but for now I'm afraid the current state 
of video scaling is rather complicated and could be very hard to extend.
A major rewrite of these parts would be better to allow hardware scaling 
or thing like that when changing the window size for example.

Doing it only for monochrome would be simpler, but it's not trivial 
nevertheless. You can have a look at the current sources.
