commit 3b3d216d2966fc97f2fefd5606e92ebec961daa8
Author: Robert Bragg <robert linux intel com>
Date: Wed Sep 7 23:44:37 2011 +0100
pipeline: split out all core state apis
Since cogl-pipeline.c has become very unwieldy this make a start at
trying to shape this code back into a manageable state. This patche
moves all the API relating to core pipeline state into
cogl-pipeline-state.c. This doesn't move code relating to layer state
out nor does it move any of the code supporting the core design
of CoglPipeline itself.
This change alone factors out 2k lines of code from cogl-pipeline.c
which is obviously a good start. The next step will be to factor
out the layer state and then probably look at breaking all of this
state code down into state-groups.

- * <listitem><para>CONSTANT: The constant set via cogl_pipeline_set_blend_constant()</para></listitem>
- * </itemizedlist>
- *
- * The source names can be used according to the
- * <link linkend="cogl-Blend-String-syntax">color-source and factor syntax</link>,
- * so for example "(1-SRC_COLOR[A])" would be a valid factor, as would
- * "(CONSTANT[RGB])"
- *
- * These can also be used as factors:
- * <itemizedlist>
- * <listitem>0: (0, 0, 0, 0)</listitem>
- * <listitem>1: (1, 1, 1, 1)</listitem>
- * <listitem>SRC_ALPHA_SATURATE_FACTOR: (f,f,f,1) where f = MIN(SRC_COLOR[A],1-DST_COLOR[A])</listitem>
- * </itemizedlist>
