		brechtUnsubmitted Not Done Inline Actions This seems to permanently disable the GPU module when Python tries to import it. But it can be initialized later on still, so this seems wrong. Maybe it is better to disallow important the module at the top level. @Bastien Montagne (mont29) say in the task it wasn't necessary, but to me that seems like the cleaner solution? brecht: This seems to permanently disable the GPU module when Python tries to import it.

		mano-wiiAuthorUnsubmitted Done Inline Actions I agree, I didn't think of this. With a small change in the C code the python files can be initialized before the GPU. Another solution would be to check if the GPU is initialized before calling each function. I tried to avoid this because some drawing functions can be called too often and it would be good to avoid overhead. But the overhead is small. editing... mano-wii: I agree, I didn't think of this.
