pipeline: Add a snippet hook for the texture lookup This adds a per-layer snippet hook for the texure lookup. Here the snippet can modify the texture coordinates used for the lookup or modify the texel resulting from the lookup. This is the first per-layer hook so this also adds the COGL_PIPELINE_LAYER_STATE_FRAGMENT_SNIPPETS state and all of the boilerplate needed to make that work. Most of the functions used by the pipeline state to manage the snippet list has been moved into cogl-pipeline-snippet.c so that it can be shared with the layer state.

snippet: Add a 'replace' string If present, the 'replace' string will be used instead of whatever code would normally be invoked for that hook point. It will also replace any previous snippets. Reviewed-by: Robert Bragg <robert@linux.intel.com>

pipeline: Add a snippet hook for the texture lookup This adds a per-layer snippet hook for the texure lookup. Here the snippet can modify the texture coordinates used for the lookup or modify the texel resulting from the lookup. This is the first per-layer hook so this also adds the COGL_PIPELINE_LAYER_STATE_FRAGMENT_SNIPPETS state and all of the boilerplate needed to make that work. Most of the functions used by the pipeline state to manage the snippet list has been moved into cogl-pipeline-snippet.c so that it can be shared with the layer state.
