Make create_transform_snippet method more consistent. Abstract TransferFunction struct: convert it to ColorOpSnippet. This transform snippet will be defined by these ColorOpSnippets. These ColorOpSnippets are similar to the prescriptive DRM API for color transformation. A standard transform snippet would have as ColorOpSnippets: 1. eotf 2. luminance_mapping 3. color_space_mapping 4. inv_eotf Update uniforms the same way the transform snippet is defined. Update color transform key to consider how the transform snippet is generated. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4144>
