GLenum _mesa_base_fbo_format	(	GLcontext *	ctx,
		GLenum	internalFormat
	)

Given an internal format token for a render buffer, return the corresponding base format.

This is very similar to _mesa_base_tex_format() but the set of valid internal formats is somewhat different.

Returns:

one of GL_RGB, GL_RGBA, GL_STENCIL_INDEX, GL_DEPTH_COMPONENT GL_DEPTH_STENCIL_EXT or zero if error.

Remove any texture or renderbuffer attached to the given attachment point.

Update reference counts, etc.

Bind a texture object to an attachment point.

The previous binding, if any, will be removed first.

void _mesa_test_framebuffer_completeness	(	GLcontext *	ctx,
		struct gl_framebuffer *	fb
	)

Test if the given framebuffer object is complete and update its Status field with the results.

Calls the ctx->Driver.ValidateFramebuffer() function to allow the driver to make hardware-specific validation/completeness checks. Also update the framebuffer's Width and Height fields if the framebuffer is complete.
