renderer: Expose winsys ID setter/getters This adds API to let you override the choice of Cogl's winsys backend. Previously it was only possible to override the winsys using the COGL_RENDERER environment variable, but it's useful for something like Clutter to be able to control the winsys via API without needing environment variable tricks.

Adds initial GLES2 integration support This makes it possible to integrate existing GLES2 code with applications using Cogl as the rendering api. Currently all GLES2 usage is handled with separate GLES2 contexts to ensure that GLES2 api usage doesn't interfere with Cogl's own use of OpenGL[ES]. The api has been designed though so we can provide tighter integration later. The api would allow us to support GLES2 virtualized on top of an OpenGL/GLX driver as well as GLES2 virtualized on the core rendering api of Cogl itself. Virtualizing the GLES2 support on Cogl will allow us to take advantage of Cogl debugging facilities as well as let us optimize the cost of allocating multiple GLES2 contexts and switching between them which can both be very expensive with many drivers. As as a side effect of this patch Cogl can also now be used as a portable window system binding API for GLES2 as an alternative to EGL. Parts of this patch are based on work done by Tomeu Vizoso <tomeu.vizoso@collabora.com> who did the first iteration of adding GLES2 API support to Cogl so that WebGL support could be added to webkit-clutter. This patch adds a very minimal cogl-gles2-context example that shows how to create a gles2 context, clear the screen to a random color and also draw a triangle with the cogl api.

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.

Remove all internal includes of cogl.h The cogl.h header is meant to be the public header for including the 1.x api used by Clutter so we should stop using that as a convenient way to include all likely prototypes and typedefs. Actually we already do a good job of listing the specific headers we depend on in each of the .c files we have so mostly this patch just strip out the redundant includes for cogl.h with a few fixups where that broke the build.

CoglFuncPtr
Don't use the 'NULL' GModule to resolve GL symbols Previously, _cogl_get_proc_address had a fallback to resolve the symbol using g_module_open(NULL) to get the symbol from anywhere in the address space. The EGL backend ends up using this on some drivers because eglGetProcAddress isn't meant to return a pointer for core functions. This causes problems if something in the process is linking against a different GL library, for example Cairo may be linking against libGL itself. In this case it may end up resolving symbols from the GL library even if GLES is being used. This patch removes the fallback. The EGL version now has its own fallback instead which passes the existing libgl_module from the renderer to g_module_symbol so that it should only get symbols from that library or its dependency chain. The GLX and WGL winsys only call glXGetProcAddress and wglGetProcAddress. The stub winsys does however continue using the global symbol lookup. The internal _cogl_get_proc_address function has been renamed to _cogl_renderer_get_proc_address because it needs a connected renderer to work so it could be considered to be a renderer method. The pointer to the renderer is passed down to the winsys backends so that it can use the data attached to the renderer to get the module pointers. https://bugzilla.gnome.org/show_bug.cgi?id=655412 Reviewed-by: Robert Bragg <robert@linux.intel.com>

Don't use eglGetProcAddress to retrieve core functions According to the EGL spec, eglGetProcAddress should only be used to retrieve extension functions. It also says that returning non-NULL does not mean the extension is available so you could interpret this as saying that the function is allowed to return garbage for core functions. This seems to happen at least for the Android implementation of EGL. To workaround this the winsys's are now passed down a flag to say whether the function is from the core API. This information is already in the gl-prototypes headers as the minimum core GL version and as a pair of flags to specify whether it is available in core GLES1 and GLES2. If the function is in core the EGL winsys will now avoid using eglGetProcAddress and always fallback to querying the library directly with the GModule API. The GLX winsys is left alone because glXGetProcAddress apparently supports querying core API and extension functions. The WGL winsys could ideally be changed because wglGetProcAddress should also only be used for extension functions but the situation is slightly different because WGL considers anything from GL > 1.1 to be an extension so it would need a bit more information to determine whether to query the function directly from the library. The SDL winsys is also left alone because it's not as easy to portably determine which GL library SDL has chosen to load in order to resolve the symbols directly. Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 72089730ad06ccdd38a344279a893965ae68cec1) Since we aren't able to break API on the 1.12 branch cogl_get_proc_address is still supported but isn't easily able to determine whether the given name corresponds to a core symbol or not. For now we just assume the symbol being queried isn't part of the core GL api and update the documentation accordingly.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead.

Currently all GLES2 usage is handled with separate GLES2 contexts to ensure that GLES2 api usage doesn't interfere with Cogl's own use of OpenGL[ES]. The api has been designed though so we can provide tighter integration later. The api would allow us to support GLES2 virtualized on top of an OpenGL/GLX driver as well as GLES2 virtualized on the core rendering api of Cogl itself. Virtualizing the GLES2 support on Cogl will allow us to take advantage of Cogl debugging facilities as well as let us optimize the cost of allocating multiple GLES2 contexts and switching between them which can both be very expensive with many drivers. As as a side effect of this patch Cogl can also now be used as a portable window system binding API for GLES2 as an alternative to EGL. Parts of this patch are based on work done by Tomeu Vizoso <tomeu.vizoso@collabora.com> who did the first iteration of adding GLES2 API support to Cogl so that WebGL support could be added to webkit-clutter. This patch adds a very minimal cogl-gles2-context example that shows how to create a gles2 context, clear the screen to a random color and also draw a triangle with the cogl api.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Add a vtable of indirection to the winsys code So that we can dynamically select what winsys backend to use at runtime we need to have some indirection to how code accesses the winsys instead of simply calling _cogl_winsys* functions that would collide if we wanted to compile more than one backend into Cogl.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Add missing _cogl_winsys_has_feature prototype This adds a private prototype for _cogl_winsys_has_feature in cogl-winsys-private.h to avoid compilation warnings.

rename winsys files to be more consistent This tries to make the naming style of files under cogl/winsys/ consistent with other cogl source files. In particular private header files didn't have a '-private' infix.
