Options

Floating point renderbuffer support

It is now possible to use floating point renderbuffers and read the data back from them. The changes include: - Modified glReadPixels so that it always uses the blitter to copy the data to the external buffer. - Added new types to both Framebuffer and some utility functions. - Added the new ValidReadPixelsFormatType function to validate the glReadPixels format/type combo, which had a bit more possibilities than the RGBA/UNSIGNED BYTE combo previously used.
