Thanks for answering. I understand now why that doesn't really fit in GapiDraw.
Here is yet another question... I am creating a tile base game, and I need to render to an area that has around 64 pixels left, right, top and bottom of the screen.
What I do is create a larger surface, draw what needs to be drawn, then copy the viewable part to the backbuffer and flip it.
Is this the best way? Is there another way that would be better?
Thanks!
