Sylvain Munaut a6a5ad8616 fosphor/cl: Fix tex coordinate in bicubic color mapping shader 
The texture coordinates didn't match what the normal OpenGL bilinear
mapper does. It was off by half a texel.

This is needed because the color in the texture is considered to be a
sample at the center of the texel. (hence 0.5f, 0.5f offset removed)

For more details on bilinear from OpenGL :
