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>

pipeline: Split more code out from cogl-pipeline.c This splits out the core CoglPipelineLayer support code from cogl-pipeline.c into cogl-pipeline-layer.c; it splits out the debugging code for dumping a pipeline to a .dot file into cogl-pipeline-debug.c and it splits the CoglPipelineNode support which is shared between CoglPipeline and CoglPipelineLayer into cogl-node.c. Note: cogl-pipeline-layer.c only contains the layer code directly relating to CoglPipelineLayer objects; it does not contain any _cogl_pipeline API relating to how CoglPipeline tracks and manipulates layers.

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.

This can be used to alter the application of the layer user matrix to a texture coordinate or it can bypass it altogether.
