Improve scaling and separate sampler state from texture state gl: Unify all texture cache objects under one structure separate by use case gl: Texture cache fixes - Acquire lock when finding matching textures - Account for swizzled surfaces when deciding whether to cpu memcpy - Handle swizzled images on the GPU
