hmm, the problem with making that change is that IIUC this will break on
GL ES, since it has imaging extension and glBlendEquation is standard there.
Gerrit: any thoughts on what the best way to handle this is? Something like:
if(hasExtension(ARB_imaging)
else if(hasExtOrversion(ARB_imaging, 0x0104, 0x0200)
?
