Currently OpenCL devices are packing images into a single texture, which means technically number of textures is not limited here. Now OpenCL will use same number of textures as CPU. If we want to bump number of textures further, this values are to be modified in sync. NOTE OpenCL still does not support float textures. Original patch from a guy called bliblubli in the tracker with some own modifications. Reviewers: brecht, dingto, sergey Differential Revision: https://developer.blender.org/D1530
