Aaargh! This is exactly what I don't like about these sort of
solutions.
Why is the "Canvas API" part of either a toolkit or a desktop
environment? Why do they have different (even if only slightly so)
APIs?
As an example of the Right Way(TM) to do it, I'd like to use OpenGL.
It's the same regardless of driver, hardware or operating system. The
only missing part is setting up the display, which is done
differently on different platforms.
My point is that whether you're using glx to set up OpenGL on X, or
wgl to set up a display on Win32, OpenGL is still OpenGL. Use SDL or
something to set up the display, and your code can be *totally*
portable to any platform that has OpenGL.
