Setting up layer combine functions and blend modes is very awkward to do
programatically. This adds a parser for string based descriptions which are
more consise and readable.
E.g. a material layer combine function could now be given as:
"RGBA = ADD (TEXTURE[A], PREVIOUS[RGB])"
or
"RGB = REPLACE (PREVIOUS)"
"A = MODULATE (PREVIOUS, TEXTURE)"
The simple syntax and grammar are only designed to expose standard fixed
function hardware, more advanced combining must be done with shaders.
This includes standalone documentation of blend strings covering the aspects
that are common to blending and texture combining, and adds documentation
with examples specific to the new cogl_material_set_blend() and
cogl_material_layer_set_combine() functions.
Note: The hope is to remove the now redundant bits of the material API
before 1.0
Bug 1219 - Clean up cogl.h
* clutter/cogl/cogl.h.in:
* clutter/cogl/cogl-offscreen.h:
* clutter/cogl/cogl-path.h:
* clutter/cogl/cogl-shader.h:
* clutter/cogl/cogl-texture.h:
* clutter/cogl/cogl-types.h: Split up the massive cogl.h file
into sub-header for each section of the API.
* clutter/cogl/gl/*:
* clutter/cogl/gles/*: Update the GL and GLES implementations
of COGL to cope with the new header structure.
* doc/reference/cogl/Makefile.am: Fix symbol retrieval.
* cogl/Makefile.am:
* cogl/cogl-docs.sgml:
* cogl/version.xml.in
* clutter/version.xml.in
Add full version (including minor) to docs.
Add version to COGL docs
* doc/reference/cogl/Makefile.am: Ignore cogl/gl and cogl/gles
when building the documentation.
* clutter/cogl/cogl.h.in: Add sections in the header file.
* clutter/clutter-docs.sgml: Add index for the 0.8 symbols.
* clutter/Makefile.am:
* cogl/Makefile.am: Revert back, as EXTRA_DIST has been defined
by gtk-doc.make and automake-1.9 complains loudly about a
redefinition of EXTRA_DIST.
