except for curves, that's still missing from the OpenColorIO GLSL shader. The pixels are stored in a half float texture, converterd from full float with native GPU instructions and SIMD on the CPU, so it should be pretty quick. Using a GLSL shader is useful for GPU render because it avoids a copy through CPU memory.
