Avoid polluting glstate in GetTempFBO().

Browse Source 
Since we do this "late", we might overwrite important settings, such as
stencil, color masks, etc.

This affects both depal and fbo shader blending.

Didn't do it for all ClearBuffer()s, since I'm worried some might be
intentionally resetting state.
