I'd rather fix the handling of the format table. Floating point
formats are another case where we should be doing extension checks,
rather than having entries for those and only doing the extension
check in CheckDeviceFormat. We may even want to support different
internal formats for different uses... not sure about that one yet.
(The problem there is that currently eg. D3DFMT_R5G6B5 isn't supported
as FBO attachment, but would be if we used eg. GL_RGBA8 as internal
