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.

texture-pixmap-x11: Move GLX code to cogl-winsys-glx.c This moves the GLX specific code from cogl-texture-pixmap-x11.c into cogl-winsys-glx.c. If we want the winsys components to by dynamically loadable then we can't have GLX code scattered outside of cogl-winsys-glx.c. This also sets us up for supporting the EGL_texture_from_pixmap extension which is almost identical to the GLX_texture_from_pixmap extension.

cogl: rename CoglMaterial -> CoglPipeline This applies an API naming change that's been deliberated over for a while now which is to rename CoglMaterial to CoglPipeline. For now the new pipeline API is marked as experimental and public headers continue to talk about materials not pipelines. 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.

cogl-renderer: Move the XEvent filters to be generic for all renderers Instead of having cogl_renderer_xlib_add_filter and friends there is now cogl_renderer_add_native_filter which can be used regardless of the backend. The callback function for the filter now just takes a void pointer instead of an XEvent pointer which should be interpreted differently depending on the backend. For example, on Xlib it would still be an XEvent but on Windows it could be a MSG. This simplifies the code somewhat because the _cogl_xlib_add_filter no longer needs to have its own filter list when a stub renderer is used because there is always a renderer available. cogl_renderer_xlib_handle_event has also been renamed to cogl_renderer_handle_native_event.

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-renderer: Move the XEvent filters to be generic for all renderers Instead of having cogl_renderer_xlib_add_filter and friends there is now cogl_renderer_add_native_filter which can be used regardless of the backend. The callback function for the filter now just takes a void pointer instead of an XEvent pointer which should be interpreted differently depending on the backend. For example, on Xlib it would still be an XEvent but on Windows it could be a MSG. This simplifies the code somewhat because the _cogl_xlib_add_filter no longer needs to have its own filter list when a stub renderer is used because there is always a renderer available. cogl_renderer_xlib_handle_event has also been renamed to cogl_renderer_handle_native_event. This just forwards the event on to all of the listeners. The backend renderer is expected to register its own event filter if it wants to process the events in some way.

cogl: rename CoglMaterial -> CoglPipeline This applies an API naming change that's been deliberated over for a while now which is to rename CoglMaterial to CoglPipeline. For now the new pipeline API is marked as experimental and public headers continue to talk about materials not pipelines. 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.

* storage is changing so it knows it may need to bind a new texture
* if the CoglTexture is reused with the same texture unit. */
Add a strong CoglTexture type to replace CoglHandle As part of the on going, incremental effort to purge the non type safe CoglHandle type from the Cogl API this patch tackles most of the CoglHandle uses relating to textures. We'd postponed making this change for quite a while because we wanted to have a clearer understanding of how we wanted to evolve the texture APIs towards Cogl 2.0 before exposing type safety here which would be difficult to change later since it would imply breaking APIs. The basic idea that we are steering towards now is that CoglTexture can be considered to be the most primitive interface we have for any object representing a texture. The texture interface would provide roughly these methods: cogl_texture_get_width cogl_texture_get_height cogl_texture_can_repeat cogl_texture_can_mipmap cogl_texture_generate_mipmap; cogl_texture_get_format cogl_texture_set_region cogl_texture_get_region Besides the texture interface we will then start to expose types corresponding to specific texture types: CoglTexture2D, CoglTexture3D, CoglTexture2DSliced, CoglSubTexture, CoglAtlasTexture and CoglTexturePixmapX11. We will then also expose an interface for the high-level texture types we have (such as CoglTexture2DSlice, CoglSubTexture and CoglAtlasTexture) called CoglMetaTexture. CoglMetaTexture is an additional interface that lets you iterate a virtual region of a meta texture and get mappings of primitive textures to sub-regions of that virtual region. Internally we already have this kind of abstraction for dealing with sliced texture, sub-textures and atlas textures in a consistent way, so this will just make that abstraction public. The aim here is to clarify that there is a difference between primitive textures (CoglTexture2D/3D) and some of the other high-level textures, and also enable developers to implement primitives that can support meta textures since they can only be used with the cogl_rectangle API currently. The thing that's not so clean-cut with this are the texture constructors we have currently; such as cogl_texture_new_from_file which no longer make sense when CoglTexture is considered to be an interface. These will basically just become convenient factory functions and it's just a bit unusual that they are within the cogl_texture namespace. It's worth noting here that all the texture type APIs will also have their own type specific constructors so these functions will only be used for the convenience of being able to create a texture without really wanting to know the details of what type of texture you need. Longer term for 2.0 we may come up with replacement names for these factory functions or the other thing we are considering is designing some asynchronous factory functions instead since it's so often detrimental to application performance to be blocked waiting for a texture to be uploaded to the GPU.

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-texture: Share the common code in the set_region virtual There was a lot of common code that was copied to all of the backends to convert the data to a suitable format and wrap it into a CoglBitmap so that it can be passed to _cogl_texture_driver_upload_subregion_to_gl.

cogl-texture: Share the common code in the get_data virtual Previously cogl_texture_get_data would pretty much directly pass on to the get_data texture virtual function. This ended up with a lot of common code that was copied to all of the backends. For example, the method is expected to return the required data size if the data pointer is NULL and to calculate its own rowstride if the rowstride is 0. Also it needs to convert the downloaded data if GL can't support that format directly. This patch moves the common code to cogl-texture.c so the virtual is always called with a format that can be downloaded directly by GL and with a valid rowstride. If the download fails then the virtual can return FALSE in which case cogl-texture will use the draw and read fallback.

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.
