Pekka Paalanen 4d5b2f3410 gl-renderer: add shader bit input_is_premult ... Add a new shader requirements bit input_is_premult which says whether the texture sampling results in premultiplied alpha or not. Currently this can be deduced fully from the shader texture variant, but in the future there might a protocol extension to explicitly control it. Hence the need for a new bit. yuva2rgba() is changed to produce straight alpha always. This makes sample_input_texture() sometimes produce straight or premultiplied alpha. The input_is_premult bit needs to match sample_input_texture() behavior. Doing this should save three multiplications in the shader for straight alpha formats.
