FrameBuffer : Added GetSize() & tweaked Bind()/Unbind() with size update for correct rendering.

to get M_PI from the platform headers and cast it to float.

to show how it can be used.

vertexbuffer : added TexCoordExt, which is the same as TexCoord but means "use vec4 for TexCoord"

when a stream is not found in the vertex declaration at bind time.

empty vertex declarations even though many video card
drivers do not support them — and they should.

internal format is then automatically deduced. Only a few 8-bit RGB
or RGBA formats are supported for now.

with a null argument, and the texture stuff was completely messed up.

texture class refactor.

hardcoded and only the fractal demo uses it, but everything will eventually switch.

calls so that they take a number of vertices or indexes, not elements.

accept them as variable names.

successfully parse a few of our full GLSL/HLSL shaders.
