What do you mean by this?

It is undocumented, but roRegion does implement ifDraw2d, and it's the only (easy) way to do clipping when drawing directly to a bitmap or screen.

I am particularly interested in creating regions right from the roScreen buffer which apparently works except for the scaling that is returned.
I've never had luck trying to draw a portion of the screen to a bitmap or the screen. This is what I was eluding to in the previous thread. In theory it should work, though. Again, could you explain what you mean by "except for the scaling that is returned"?
