This migrates all the GLX window system code down from the Clutter backend code into a Cogl winsys. Moving OpenGL window system binding code down from Clutter into Cogl is the biggest blocker to having Cogl become a standalone 3D graphics library, so this is an important step in that direction.

|
|
* Error enumeration for Cogl
|
|
*
|
|
* The @COGL_ERROR_UNSUPPORTED error can be thrown for a variety of
|
|
* reasons. For example:
|
|
*
|
|
* <itemizedlist>
|
|
* <listitem><para>You've tried to use a feature that is not
|
|
* advertised by cogl_get_features(). This could happen if you create
|
|
* a non-sliced texture with a non-power-of-two size when
|
|
* %COGL_FEATURE_TEXTURE_NPOT is not advertised.</para></listitem>
|
|
* <listitem><para>The GPU can not handle the configuration you have
|
|
* requested. An example might be if you try to use too many texture
|
|
* layers in a single #CoglPipeline</para></listitem>
|
|
* <listitem><para>The driver does not support some
|
|
* configuration.</para></listiem>
|
|
* </itemizedlist>
|
|
*
|
|
* Currently this is only used by Cogl API marked as experimental so
|
|
* this enum should also be considered experimental.
