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.h: define __COGL_H_INSIDE__ Ideally we wouldn't have exposed cogl-texture-pixmap-x11.h as a top level header and would have just automatically included it in cogl.h but we already have code that assumes it can be directly included. This ensures we define __COGL_H_INSIDE__ as a reminder that it is a top level header in case we later need to include other cogl internal cogl headers which would cause a build time error without this defined.

cogl: declare experimental symbols consistently We had several different ways of exposing experimental API, in one case the symbols had no special suffix, in two other ways the symbols were given an _EXP suffix but in different ways. This makes all experimental API have an _EXP suffix which is handled using #defines in the header so the prototypes in the .c and .h files don't have the suffix. The documented reason for the suffix is so that anyone watching Cogl for ABI changes who sees symbols disappear will hopefully understand what's going on.

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 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.

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.
