This splits up cogl-ext-functions.h in to sets of prototypes that can be included separately so that we can include just core gles1 or gles2 functions without any extensions. Since eglGetProcAddress can not be used to query core client APIs and some implementations (notably on Android) can return a garbage pointer instead of NULL this will allow us to explicitly check when to use eglGetProcAddress and when to use dlsym().

/* This is included multiple times with different definitions for

|
|
* COGL_EXT_BEGIN:
|
|
*
|
|
* @name: a unique symbol name for this feature
|
|
*
|
|
* @min_gl_major: the major part of the minimum GL version where these
|
|
* functions are available in core, or 255 if it isn't available in
|
|
* any version.
|
|
* @min_gl_minor: the minor part of the minimum GL version where these
|
|
* functions are available in core, or 255 if it isn't available in
|
|
* any version.
|
|
*
|
|
* @gles_availability: flags to specify which versions of GLES the
|
|
* functions are available in. Should be a combination of
|
|
* COGL_EXT_IN_GLES and COGL_EXT_IN_GLES2.
|
|
*
|
|
* @extension_suffixes: A zero-separated list of suffixes in a
|
|
* string. These are appended to the extension name to get a complete
|
|
* extension name to try. The suffix is also appended to all of the
|
|
* function names. The suffix can optionally include a ':' to specify
|
|
* an alternate suffix for the function names.
|
|
*
|
|
* @extension_names: A list of extension names to try. If any of these
|
|
* extensions match then it will be used.
