At the moment, only win32 uses double-buffering by default.
Is it required? Useful?
Does it limit the number of paints we can do per second because of the synchronization that happens when we swap_buffers?

This needs testing with:


Same for Linux, do we want to enable double buffering there?
Does it work reliably?

Also, when not using double buffering, we can optimize repaints to only paste the fbo contents on the area of the window that needs updating instead of the whole window.
