yep. you should be able to control this on low level with
[GEMglBlendFunc] and [GEMglAlphaFunc]

well, if you only want to change the blending between a surface and the
background, then you should be able to do this without [gemframebuffer],

but then you would have to re-implement the default fragment shader
which is probably not worth it.

i wonder why i miss something like ftransform() for fragment shaders.
