Detailed Description

PVR sprite context.

You should use this more human readable format for specifying your sprite contexts, and then compile them into sprite headers when you are ready to start using them.

Unfortunately, it seems that Doxygen chokes up a little bit on this structure, and others like it. The documentation should still be mostly understandable though...
