It should be relatively easy, as there are few of them only.

I'm not sure what is the request or why. Glsl Optimizer just takes an input GLSL shader, and writes an output GLSL (or Metal) shader. If your shader has a thing like uniform sampler2D gm_BaseTexture in there, then it's there. What special treatment they should get that does not work today?
