Matthew Waters 6bb113f685 gl: add a sync meta for synchronizing across GL contexts A context can create a GLsync object that can be waited on in order to ensure that GL resources created in one context are able to be used in another shared context without any chance of reading invalid data. This meta would be placed on buffers that are known to cross from one context to another. The receiving element would then wait on the sync object to ensure that the data to be used is complete.		2017-12-09 19:31:51 +00:00

 * Changes:
 *  - Namespace COGL -> GST_GL
 *  - remove gl from each function (i.e. glTexImage2D -> TexImage2D)

/* The files in this folder are included multiple times with different
 * definitions for these macros. The macros are given the following arguments:
 *
 * GST_GL_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
 * GST_GL_API_GLES and GST_GL_API_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.
