CoglPipelineAlphaFunc
since: 13
Description [src]
Alpha testing happens before blending primitives with the framebuffer and
gives an opportunity to discard fragments based on a comparison with the
incoming alpha value and a reference alpha value. The CoglPipelineAlphaFunc
determines how the comparison is done.
