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.

[cogl] Add a PANGO debug flag for CoglPango use The CoglPango code falls under the COGL "jurisdiction"; this means that it cannot include Clutter headers unless strictly necessary. The CoglPangoRenderer code was using the CLUTTER_NOTE() macro. Now that COGL has it's own COGL_NOTE() similar macro, CoglPango should use that and avoid including clutter-debug.h (which pulls in clutter-private.h which in turn pulls in clutter-actor.h). A new flag, COGL_DEBUG_PANGO, has been added to the COGL debug flags.

The outline colors rotate in order from red to green to blue which can also help confirm the order that your geometry really drawn. The outlines are not affected by the current material state, so if you e.g. have a blending bug where geometry mysteriously disappears this can confirm if the underlying rectangles are actually being emitted but blending is causing them to be invisible.

cogl-framebuffer: Use the FBO extension for color sizes OpenGL 3.0 deprecated querying of the GL_{RED,GREEN,BLUE}_BITS constants, and the FBO extension provides a mechanism to query for the color buffer sizes which *should* work even with the default framebuffer. Unfortunately, this doesn't seem to hold for Mesa - so we just use this for the offscreen CoglFramebuffer type, and we fall back to glGetIntegerv() for the onscreen one. http://bugzilla.openedhand.com/show_bug.cgi?id=2094

Add a CoglTexturePixmapX11 texture backend This is a publicly exposed texture backend to create a texture which contains the contents of an X11 pixmap. The API is currently marked as experimental. The backend internally holds a handle to another texture. All of the backend virtuals simply redirect to the internal texture. The texture can optionally be automatically updated if the automatic_updates parameter is TRUE. If set then Cogl will listen for damage events on the pixmap and update the texture accordingly. Alternatively a damage object can be created externally and passed down to Cogl. The updates can be performed with XGetImage, XShmGetImage or the GLX_EXT_texture_pixmap extension. If the TFP extension is used it will optionally try to create a rectangle texture if the driver does not support NPOTs or it is forced through the COGL_PIXMAP_TEXTURE_RECTANGLE or CLUTTER_PIXMAP_TEXTURE_RECTANGLE environment variables. If the GLXFBConfig does not support mipmapping then it will fallback to using X{Shm,}GetImage. It keeps a separate texture around for this so that it can later start using the TFP texture again if the texture is later drawn with mipmaps disabled.

[cogl] Move debugging to a configure-time switch Currently, COGL depends on defining debug symbols by manually modifying the source code. When it's done, it will forcefully print stuff to the console. Since COGL has also a pretty, runtime selectable debugging API we might as well switch everything to it. In order for this to happen, configure needs a new: --enable-cogl-debug command line switch; this will enable COGL debugging, the CoglHandle debugging and will also turn on the error checking for each GL operation. The default setting for the COGL debug defines is off, since it slows down the GL operations; enabling it for a particular debug build is trivial, though.

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

CoglMaterial: Implements sparse materials design This is a complete overhaul of the data structures used to manage CoglMaterial state. We have these requirements that were aiming to meet: (Note: the references to "renderlists" correspond to the effort to support scenegraph level shuffling of Clutter actor primitives so we can minimize GPU state changes) Sparse State: We wanted a design that allows sparse descriptions of state so it scales well as we make CoglMaterial responsible for more and more state. It needs to scale well in terms of memory usage and the cost of operations we need to apply to materials such as comparing, copying and flushing their state. I.e. we would rather have these things scale by the number of real changes a material represents not by how much overall state CoglMaterial becomes responsible for. Cheap Copies: As we add support for renderlists in Clutter we will need to be able to get an immutable handle for a given material's current state so that we can retain a record of a primitive with its associated material without worrying that changes to the original material will invalidate that record. No more flush override options: We want to get rid of the flush overrides mechanism we currently use to deal with texture fallbacks, wrap mode changes and to handle the use of highlevel CoglTextures that need to be resolved into lowlevel textures before flushing the material state. The flush options structure has been expanding in size and the structure is logged with every journal entry so it is not an approach that scales well at all. It also makes flushing material state that much more complex. Weak Materials: Again for renderlists we need a way to create materials derived from other materials but without the strict requirement that modifications to the original material wont affect the derived ("weak") material. The only requirement is that its possible to later check if the original material has been changed. A summary of the new design: A CoglMaterial now basically represents a diff against its parent. Each material has a single parent and a mask of state that it changes. Each group of state (such as the blending state) has an "authority" which is found by walking up from a given material through its ancestors checking the difference mask until a match for that group is found. There is only one root node to the graph of all materials, which is the default material first created when Cogl is being initialized. All the groups of state are divided into two types, such that infrequently changed state belongs in a separate "BigState" structure that is only allocated and attached to a material when necessary. CoglMaterialLayers are another sparse structure. Like CoglMaterials they represent a diff against their parent and all the layers are part of another graph with the "default_layer_0" layer being the root node that Cogl creates during initialization. Copying a material is now basically just a case of slice allocating a CoglMaterial, setting the parent to be the source being copied and zeroing the mask of changes. Flush overrides should now be handled by simply relying on the cheapness of copying a material and making changes to it. (This will be done in a follow on commit) Weak material support will be added in a follow on commit.

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 debug: Makes COGL_DEBUG=all|verbose|help more useful COGL_DEBUG=all wasn't previously useful as there are several options that change the behaviour of Cogl and all together wouldn't help anyone debug anything. This patch makes it so COGL_DEBUG=all|verbose now only enables options that don't change the behaviour of Cogl, i.e. they only affect the amount of noise we'll print to a terminal. In addition to that this patch also improves the output from COGL_DEBUG=help so we now print a table of options including one liner descriptions of what each option enables.

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.

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.
