Add runtime debug messages for COGL Clutter is able to show debug messages written using the CLUTTER_NOTE() macro at runtime, either by using an environment variable: CLUTTER_DEBUG=... or by using a command line switch: --clutter-debug=... --clutter-no-debug=... Both are parsed during the initialization process by using the GOption API. COGL would benefit from having the same support. In order to do this, we need a cogl_get_option_group() function in COGL that sets up a GOptionGroup for COGL and adds a pre-parse hook that will check the COGL_DEBUG environment variable. The OptionGroup will also install two command line switches: --cogl-debug --cogl-no-debug With the same semantics of the Clutter ones. During Clutter initialization, the COGL option group will be attached to the GOptionContext used to parse the command line options passed to a Clutter application. Every debug message written using: COGL_NOTE (SECTION, "message format", arguments); Will then be printed only if SECTION was enabled at runtime. This whole machinery, like the equivalent one in Clutter, depends on a compile time switch, COGL_ENABLE_DEBUG, which is enabled at the same time as CLUTTER_ENABLE_DEBUG. Having two different symbols allows greater granularity.

profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place.

material: Adds backend abstraction for fragment processing As part of an effort to improve the architecture of CoglMaterial internally this overhauls how we flush layer state to OpenGL by adding a formal backend abstraction for fragment processing and further formalizing the CoglTextureUnit abstraction. There are three backends: "glsl", "arbfp" and "fixed". The fixed backend uses the OpenGL fixed function APIs to setup the fragment processing, the arbfp backend uses code generation to handle fragment processing using an ARBfp program, and the GLSL backend is currently only there as a formality to handle user programs associated with a material. (i.e. the glsl backend doesn't yet support code generation) The GLSL backend has highest precedence, then arbfp and finally the fixed. If a backend can't support some particular CoglMaterial feature then it will fallback to the next backend. This adds three new COGL_DEBUG options: * "disable-texturing" as expected should disable all texturing * "disable-arbfp" always make the arbfp backend fallback * "disable-glsl" always make the glsl backend fallback * "show-source" show code generated by the arbfp/glsl backends

cogl: improves header and coding style consistency We've had complaints that our Cogl code/headers are a bit "special" so this is a first pass at tidying things up by giving them some consistency. These changes are all consistent with how new code in Cogl is being written, but the style isn't consistently applied across all code yet. There are two parts to this patch; but since each one required a large amount of effort to maintain tidy indenting it made sense to combine the changes to reduce the time spent re indenting the same lines. The first change is to use a consistent style for declaring function prototypes in headers. Cogl headers now consistently use this style for prototypes: return_type cogl_function_name (CoglType arg0, CoglType arg1); Not everyone likes this style, but it seems that most of the currently active Cogl developers agree on it. The second change is to constrain the use of redundant glib data types in Cogl. Uses of gint, guint, gfloat, glong, gulong and gchar have all been replaced with int, unsigned int, float, long, unsigned long and char respectively. When talking about pixel data; use of guchar has been replaced with guint8, otherwise unsigned char can be used. The glib types that we continue to use for portability are gboolean, gint{8,16,32,64}, guint{8,16,32,64} and gsize. The general intention is that Cogl should look palatable to the widest range of C programmers including those outside the Gnome community so - especially for the public API - we want to minimize the number of foreign looking typedefs.

[cogl-material] Support string based blending and layer combine descriptions 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
