Implemented using GLSL API from OpenColorIO library and some general functions were added to it's c-api: - OCIO_setupGLSLDraw prepares OpenGL context for GPU-based transformation for a giver processor. This function compiles and links shader, sets up it's argument. After this transformation would be applied on an image displaying as a 2D texture. So, glaDrawPixelsTex called after OCIO_setupGLSLDraw will do a proper color space transform. - OCIO_finishGLSLDraw restores OpenGL context after all color-managed display is over. - OCIO_freeOGLState frees allocated state structure used for cacheing some GLSL-related stuff. There're some utility functions in IMB_colormanagent which are basically proxies to lower level OCIO functions but which could be used from any place in blender. Chacheing of movie clip frame on GPU is also removed now, and either glaDrawPixelsTex or glaDrawPixelsAuto are used for display now. This is so no code duplication happens now and no large textures are lurking around in GPU memory. Known issues: - Texture buffer and GLSL are no longer checking for video card capabilities, possibly could lead to some artifacts on crappy drivers/cards. - Only float buffers are displaying using GLSL, byte buffers will still use fallback display method. This is to be addressed later. - If RGB curves are used as a part of display transform, GLSL display will also be disabled. This is also thing to be solved later. Additional changes: - glaDrawPixelsTexScaled will now use RGBA16F as an internal format of storing textures when it's used to draw float buffer. This is needed so LUT are applied without precision loss.
