pipeline: split out all layer state apis As part of an on-going effort to get cogl-pipeline.c into a more maintainable state this splits out all the apis relating just to layer state. This just leaves code relating to the core CoglPipeline and CoglPipelineLayer design left in cogl-pipeline.c. This splits out around 2k more lines from cogl-pipeline.c although we are still left with nearly 4k lines so we still have some way to go! Reviewed-by: Neil Roberts <neil@linux.intel.com>

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead.

cogl-pipeline-layer: Use CoglTextureType instead of GL target enum Instead of storing the GLenum for the target of the last used texture for a layer it now stores the CoglTextureType instead. The state name has been renamed to 'texture type' instead of 'texture target'. Previously the default pipeline layer would store 0 here to represent that there is no texture. This has been changed to store COGL_TEXTURE_TYPE_2D instead which means that all pipeline layers always have a valid value for the texture type. Any places that were previously fetching the texture from a layer to determine the target (for example when generating shaders or when enabling a particular texture target) now use the texture type instead. This means they will work even for layers that don't have a texture. This also changes it so that when binding a fallback texture instead of always using a 2D texture it will now use the default texture corresponding to the texture type of the layer. That way when the generated shader tries to do a texture lookup for that type of texture it will get a valid texture object. To make this work the patch adds a default texture for 3D textures to the context and also makes the default rectangle texture actually be a rectangle texture instead of using a 2D texture.

CoglBool
Use GL_ARB_sampler_objects GL_ARB_sampler_objects provides a GL object which overrides the sampler state part of a texture object with different values. The sampler state that Cogl currently exposes is the wrap modes and filters. Cogl exposes the state as part of the pipeline layer state but without this extension GL only exposes it as part of the texture object state. This means that it won't work to use a single texture multiple times in one primitive with different sampler states. It also makes switching between different sampler states with a single texture not terribly efficient because it has to change the texture object state every time. This patch adds a cache for sampler states in a shared hash table attached to the CoglContext. The entire set of parameters for the sampler state is used as the key for the hash table. When a unique state is encountered the sampler cache will create a new entry, otherwise it will return a const pointer to an existing entry. That means we can have a single pointer to represent any combination of sampler state. Pipeline layers now just store this single pointer rather than storing all of the sampler state. The two separate state flags for wrap modes and filters have now been combined into one. It should be faster to compare the sampler state now because instead of comparing each value it can just compare the pointers to the cached sampler entries. The hash table of cached sampler states should only need to perform its more expensive hash on the state when a property is changed on a pipeline, not every time it is flushed. When the sampler objects extension is available each cached sampler state will also get a sampler object to represent it. The common code to flush the GL state will now simply bind this object to a unit instead of flushing the state though the CoglTexture when possible. Reviewed-by: Robert Bragg <robert@linux.intel.com>

Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

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.

cogl-pipeline-layer: Use CoglTextureType instead of GL target enum Instead of storing the GLenum for the target of the last used texture for a layer it now stores the CoglTextureType instead. The state name has been renamed to 'texture type' instead of 'texture target'. Previously the default pipeline layer would store 0 here to represent that there is no texture. This has been changed to store COGL_TEXTURE_TYPE_2D instead which means that all pipeline layers always have a valid value for the texture type. Any places that were previously fetching the texture from a layer to determine the target (for example when generating shaders or when enabling a particular texture target) now use the texture type instead. This means they will work even for layers that don't have a texture. This also changes it so that when binding a fallback texture instead of always using a 2D texture it will now use the default texture corresponding to the texture type of the layer. That way when the generated shader tries to do a texture lookup for that type of texture it will get a valid texture object. To make this work the patch adds a default texture for 3D textures to the context and also makes the default rectangle texture actually be a rectangle texture instead of using a 2D texture.

Use GL_ARB_sampler_objects GL_ARB_sampler_objects provides a GL object which overrides the sampler state part of a texture object with different values. The sampler state that Cogl currently exposes is the wrap modes and filters. Cogl exposes the state as part of the pipeline layer state but without this extension GL only exposes it as part of the texture object state. This means that it won't work to use a single texture multiple times in one primitive with different sampler states. It also makes switching between different sampler states with a single texture not terribly efficient because it has to change the texture object state every time. This patch adds a cache for sampler states in a shared hash table attached to the CoglContext. The entire set of parameters for the sampler state is used as the key for the hash table. When a unique state is encountered the sampler cache will create a new entry, otherwise it will return a const pointer to an existing entry. That means we can have a single pointer to represent any combination of sampler state. Pipeline layers now just store this single pointer rather than storing all of the sampler state. The two separate state flags for wrap modes and filters have now been combined into one. It should be faster to compare the sampler state now because instead of comparing each value it can just compare the pointers to the cached sampler entries. The hash table of cached sampler states should only need to perform its more expensive hash on the state when a property is changed on a pipeline, not every time it is flushed. When the sampler objects extension is available each cached sampler state will also get a sampler object to represent it. The common code to flush the GL state will now simply bind this object to a unit instead of flushing the state though the CoglTexture when possible. Reviewed-by: Robert Bragg <robert@linux.intel.com>
