blur: Invalidate newly-bound framebuffers before rendering This signals to the GPU driver that the FBO contents do not need to be preserved. According to ARM, invalidating framebuffers after rendering and unbinding them won't do anything on Mali GPUs [1], but it improves performance with Qualcomm's Adreno GPU drivers. When tested with 2 layers of another 6-pass blur implementation, this saves ~100 µs of rendering time on an Adreno 640 GPU at 1440x3040 resolution.
