No, use paste. setPixel and getPixel are not for "quickly blit[ing] stuff". paste is more like it.

This must have been covered somewhere else but is there a list of what kinds of cards do and don't support canvas?
It'd be nice to get an idea of the % of "average users" whose computers can't do canvas.
If it's over 10% it seems like a dealbreaker to me.

No linux OS can use the canvas, to my knowledge.

I'm running Ubuntu 12.04 and as soon as the canvas is used, I will get an error, same for Fedora and Lindows. On Windows, I have no trouble.

Incorrect. Canvas support depends on GL_EXT_FRAMEBUFFER_OBJECT and related extensions, which are system (driver and video card) dependent. Most systems which support OpenGL 2.1 (and even sometimes those which only support OpenGL 1.4) will support canvases/framebuffers.

Then you don't have the right drivers, even the software emulated OpenGL (mesa) does canvases (last I heard, anyway).
