Remove mentions of the FSF address Since using addresses that might change is something that finally the FSF acknowledge as a plausible scenario (after changing address twice), the license blurb in the source files should use the URI for getting the license in case the library did not come with it. Not that URIs cannot possibly change, but at least it's easier to set up a redirection at the same place.

Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h

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.

matrix gtype: registers a boxed type for CoglMatrix To allow us to have gobject properties that accept a CoglMatrix value we need to register a GType.

cogl.h: Exclude 1.x headers if 2.0 api requested Now if COGL_ENABLE_EXPERIMENTAL_2_0_API has been defined when including cogl.h then headers that correspond to 1.x only apis that we plan to drop won't be included any more. If COGL_ENABLE_EXPERIMENTAL_API is defined then you can still mix and match 2.0 api with 1.x api in a single compilation unit. Note: it's still possible that some 1.x symbols will still be available when COGL_ENABLE_EXPERIMENTAL_2_0_API is defined since this patch doesn't go through the shared headers adding guards around deprecated functions. This only affects people playing with the experimental api. Reviewed-by: Neil Roberts <neil@linux.intel.com>

build: Make cogl.h not conditional on driver defines The main COGL header cogl.h is currently created at configure time because it conditionally includes the driver-dependent defines. This sometimes leads to a stale cogl.h with old definitions which can break the build until you clean out the whole tree and start from scratch. We can generate a stable cogl-defines.h at build time from the equivalent driver-dependent header and let cogl.h include that file instead.

Add compiler deprecation warnings This adds compiler symbol deprecation declarations for old Cogl APIs so that users can easily see via compiler warning when they are using these symbols, and also see a hint for what the apis should be replaced with. So that users of Cogl can manage when to show these warnings this introduces a scheme borrowed from glib whereby you can declare what version of the Cogl api you are using: COGL_VERSION_MIN_REQUIRED can be defined to indicate the oldest Cogl api that the application wants to use. Cogl will only warn about deprecations for symbols that were deprecated earlier than this required version. If this is left undefined then by default Cogl will warn about all deprecations. COGL_VERSION_MAX_ALLOWED can be defined to indicate the newest api that the application uses. If the application uses symbols newer than this then Cogl will give a warning about that. This patch removes the need to maintain the COGL_DISABLE_DEPRECATED guards around deprecated symbols. This patch fixes a few uses of deprecated symbols in the examples/ Reviewed-by: Neil Roberts <neil@linux.intel.com>

Adds CoglError api Although we use GLib internally in Cogl we would rather not leak GLib api through Cogl's own api, except through explicitly namespaced cogl_glib_ / cogl_gtype_ feature apis. One of the benefits we see to not leaking GLib through Cogl's public API is that documentation for Cogl won't need to first introduce the Glib API to newcomers, thus hopefully lowering the barrier to learning Cogl. This patch provides a Cogl specific typedef for reporting runtime errors which by no coincidence matches the typedef for GError exactly. If Cogl is built with --enable-glib (default) then developers can even safely assume that a CoglError is a GError under the hood. This patch also enforces a consistent policy for when NULL is passed as an error argument and an error is thrown. In this case we log the error and abort the application, instead of silently ignoring it. In common cases where nothing has been implemented to handle a particular error and/or where applications are just printing the error and aborting themselves then this saves some typing. This also seems more consistent with language based exceptions which usually cause a program to abort if they are not explicitly caught (which passing a non-NULL error signifies in this case) Since this policy for NULL error pointers is stricter than the standard GError convention, there is a clear note in the documentation to warn developers that are used to using the GError api. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit b068d5ea09ab32c37e8c965fc8582c85d1b2db46) Note: Since we can't change the Cogl 1.x api the patch was changed to not rename _error_quark() functions to be _error_domain() functions and although it's a bit ugly, instead of providing our own CoglError type that's compatible with GError we simply #define CoglError to GError unless Cogl is built with glib disabled. Note: this patch does technically introduce an API break since it drops the cogl_error_get_type() symbol generated by glib-mkenum (Since the CoglError enum was replaced by a CoglSystemError enum) but for now we are assuming that this will not affect anyone currently using the Cogl API. If this does turn out to be a problem in practice then we would be able to fix this my manually copying an implementation of cogl_error_get_type() generated by glib-mkenum into a compatibility source file and we could also define the original COGL_ERROR_ enums for compatibility too. Note: another minor concern with cherry-picking this patch to the 1.14 branch is that an api scanner would be lead to believe that some APIs have changed, and for example the gobject-introspection parser which understands the semantics of GError will not understand the semantics of CoglError. We expect most people that have tried to use gobject-introspection with Cogl already understand though that it is not well suited to generating bindings of the Cogl api anyway and we aren't aware or anyone depending on such bindings for apis involving GErrors. (GnomeShell only makes very-very minimal use of Cogl via the gjs bindings for the cogl_rectangle and cogl_color apis.) The main reason we have cherry-picked this patch to the 1.14 branch even given the above concerns is that without it it would become very awkward for us to cherry-pick other beneficial patches from master.

Add a cogl-version header This adds a version header which contains macros to define which version of Cogl the application is being compiled against. This helps applications that want to support multiple incompatible versions of Cogl at compile time. The macros are called COGL_VERSION_{MAJOR,MINOR,MICRO}. This does not match Clutter which names them CLUTTER_{MAJOR,MINOR,MICRO}_VERSION but I think the former is nicer and it at least matches Cairo and Pango. The values of the macro are defined to COGL_VERSION_*_INTERNAL which is generated by the configure script into cogl-defines.h. There is also a macro for the entire version as a string called COGL_VERSION_STRING. The internal utility macros for encoding a 3 part version number into a single integer have been moved into the new header so they can be used publicly as a convenient way to check if the version is within a particular range. There is also a COGL_VERSION_CHECK macro for the very common case that a feature will be used since a particular version of Cogl. There is a macro called COGL_VERSION which contains the pre-encoded version of Cogl being compiled against for convenience. Unlike in Clutter this patch does not add any runtime version identification mechanism. A test case is also added which just contains static asserts to sanity check the macros.

Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h

cogl: Adds experimental cogl_context_new() API This adds a new experimental function (you need to define COGL_ENABLE_EXPERIMENTAL_API to access it) which takes us towards being able to have a standalone Cogl API. This is really a minor aesthetic change for now since all the GL context creation code still lives in Clutter but it's a step forward none the less. Since our current designs introduce a CoglDisplay object as something that would be passed to the context constructor this provides a stub cogl-display.h with CoglDisplay typedef. _cogl_context_get_default() which Clutter uses to access the Cogl context has been modified to use cogl_context_new() to initialize the default context. There is one rather nasty hack used in this patch which is that the implementation of cogl_context_new() has to forcibly make the allocated context become the default context because currently all the code in Cogl assumes it can access the context using _COGL_GET_CONTEXT including code used to initialize the context.

This is part of going work to improve our texture apis with more emphasis on providing low-level access to the varying semantics of different texture types understood by the gpu instead of only trying to present a lowest common denominator api. CoglTextureRectangle is notably useful for never being restricted to power of two sizes and for being sampled with non-normalized texture coordinates which can be convenient for use a lookup tables in glsl due to not needing separate uniforms for mapping normalized coordinates to texels. Unlike CoglTexture2D though rectangle textures can't have a mipmap and they only support the _CLAMP_TO_EDGE wrap mode.

Add a Cogl texture 3D backend This adds a publicly exposed experimental API for a 3D texture backend. There is a feature flag which can be checked for whether 3D textures are supported. Although we require OpenGL 1.2 which has 3D textures in core, GLES only provides them through an extension so the feature can be used to detect that. The textures can be created with one of two new API functions :- cogl_texture_3d_new_with_size and cogl_texture_3d_new_from_data There is also internally a new_from_bitmap function. new_from_data is implemented in terms of this function. The two constructors are effectively the only way to upload data to a 3D texture. It does not work to call glTexImage2D with the GL_TEXTURE_3D target so the virtual for cogl_texture_set_region does nothing. It would be possible to make cogl_texture_get_data do something sensible like returning all of the images as a single long image but this is not currently implemented and instead the virtual just always fails. We may want to add API specific to the 3D texture backend to get and set a sub region of the texture. All of those three functions can throw a GError. This will happen if the GPU does not support 3D textures or it does not support NPOTs and an NPOT size is requested. It will also fail if the FBO extension is not supported and the COGL_TEXTURE_NO_AUTO_MIPMAP flag is not given. This could be avoided by copying the code for the GL_GENERATE_MIPMAP TexParameter fallback, but in the interests of keeping the code simple this is not yet done. This adds a couple of functions to cogl-texture-driver for uploading 3D data and querying the 3D proxy texture. prep_gl_for_pixels_upload_full now also takes sets the GL_UNPACK_IMAGE_HEIGHT parameter so that 3D textures can have padding between the images. Whenever 3D texture is uploading, both the height of the images and the height of all of the data is specified (either explicitly or implicilty from the CoglBitmap) so that the image height can be deduced by dividing by the depth.

The interface allows the development of primitive drawing APIs that can draw with high-level textures (such as atlas textures) even though the GPU doesn't natively understand these texture types. There is currently just one function that's part of this interface: cogl_meta_texture_foreach_in_region() which allows an application to resolve the internal, low-level textures of a high-level texture. cogl_rectangle() uses this API for example so that it can easily emulate the _REPEAT wrap mode for textures that the hardware can't natively handle repeating of.

The CoglMaterial API is now maintained in terms of the cogl_pipeline API internally. Currently this API is targeting Cogl 2.0 so we will have time to integrate it properly with other upcoming Cogl 2.0 work. The basic reasons for the rename are: - That the term "material" implies to many people that they are constrained to fragment processing; perhaps as some kind of high-level texture abstraction. - In Clutter they get exposed by ClutterTexture actors which may be re-inforcing this misconception. - When comparing how other frameworks use the term material, a material sometimes describes a multi-pass fragment processing technique which isn't the case in Cogl. - In code, "CoglPipeline" will hopefully be a much more self documenting summary of what these objects represent; a full GPU pipeline configuration including, for example, vertex processing, fragment processing and blending. - When considering the API documentation story, at some point we need a document introducing developers to how the "GPU pipeline" works so it should become intuitive that CoglPipeline maps back to that description of the GPU pipeline. - This is consistent in terminology and concept to OpenGL 4's new pipeline object which is a container for program objects. Note: The cogl-material.[ch] files have been renamed to cogl-material-compat.[ch] because otherwise git doesn't seem to treat the change as a moving the old cogl-material.c->cogl-pipeline.c and so we loose all our git-blame history.

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. Reviewed-by: Neil Roberts <neil@linux.intel.com>

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>

onscreen: Add CoglFrameInfo and _add_frame_callback() api Add a CoglFrameInfo object that tracks timing information for frames that are drawn. We track a frame counter and frame timing information for each CoglOnscreen. Internally a CoglFrameInfo is automatically created for each frame, delimited by cogl_onscreen_swap_buffers() or cogl_onscreen_swap_region() calls. CoglFrameInfos are delivered to applications via frame event callbacks that can be registered with a new cogl_onscreen_add_frame_callback() api. Two initial event types (dispatched on all platforms) have been defined; a _SYNC event used for throttling the frame rate of applications and a _COMPLETE event used so signify the end of a frame. Note: This new _add_frame_callback() api makes the cogl_onscreen_add_swap_complete_callback() api redundant and so it should be considered deprecated. Since the _add_swap_complete_callback() api is still experimental api, we will be looking to quickly migrate users to the new api so we can remove the old api.

Add support for main loop integration This adds two new functions: void cogl_poll_get_info (CoglContext *context, CoglPollFD **poll_fds, int *n_poll_fds, gint64 *timeout); void cogl_poll_dispatch (CoglContext *context, const CoglPollFD *poll_fds, int n_poll_fds); The application is expected to call the first function whenever it is about to block to go idle, and the second function whenever it comes out of idle. This gives Cogl winsys's the ability poll file descriptors for events. For example when handing swap complete notifications, it can report that it needs to block on a file descriptor. The two functions are backed by winsys virtual functions. There are currently no implementations. The default handler for get_info just reports no file descriptors and an infinite timeout.

Start clearly separating deprecated code This makes a start on clearly factoring the deprecated code of core Cogl into a deprecated/ directory. Ideally we want to get to the point where all code here can be re-worked in terms of the public 2.0 api so that it can be kept indefinitely for cogl 1.x api compatibility without cluttering the core code base itself. If we can do this then we can avoid maintaining the Cogl 1.x branches in parallel with master which would reduce the maintenance effort.

cogl-buffer: add an abstract class around openGL's buffer objects Buffer objects are cool! This abstracts the buffer API first introduced by GL_ARB_vertex_buffer_object and then extended to other objects. The coglBuffer abstract class is intended to be the base class of all the buffer objects, letting the user map() buffers. If the underlying implementation does not support buffer objects (or only support VBO but not FBO for instance), fallback paths should be provided.
