* Handle mismatching texture size with copy dependencies * Create copy and render textures with the minimum possible size * Only align width for comparisons, assume that height is always exact * Fix IsExactMatch size check * Allow sampler and copy textures to match textures with larger width * Delete texture ChangeSize related code * Move AdjustSize to TextureInfo and give it a better name, adjust usages * Fix GetMinimumWidthInGob when minimumWidth > width * Only update render targets that are actually cleared for clear Avoids creating textures with incorrect sizes * Delete UpdateRenderTargetState method that is not needed anymore Clears now only ever sets the render targets that will be cleared rather than all of them
