Add FBufferedUniformSampler because sampler uniforms may default bind to other locations than zero 2016-08-25 23:46:39 +00:00			`FBufferedUniformSampler InputTexture;`
Make sure we never pass a negative value to pow, and optimize gamma uniform 2016-08-15 22:01:18 +00:00			`FBufferedUniform1f InvGamma;`

- use static buffer data and a uniform to handle the texture positioning of the present shader. That's again one less write access to the buffer. The uniform method was chosen because this way a buffer update can be completely avoided, and setting a single uniform is a lot cheaper and simpler to handle. 2016-08-08 14:06:02 +00:00			`FBufferedUniform2f Scale;`
