Since 1.4 the ClutterGLXTexturePixmap is just a wrapper around ClutterX11TexturePixmap, so we can safely deprecate it. All the functionality it provided is now effectively available from the superclass or directly from Cogl.

* SECTION:clutter-glx-texture-pixmap
|
|
* @short_description: A texture which displays the content of an X Pixmap.
|
|
*
|
|
* #ClutterGLXTexturePixmap is a class for displaying the content of an
|
|
* X Pixmap as a ClutterActor. Used together with the X Composite extension,
|
|
* it allows to display the content of X Windows inside Clutter.
|
|
*
|
|
* This class used to be necessary to use the
|
|
* GLX_EXT_texture_from_pixmap extension to get fast texture
|
|
* updates. However since Clutter 1.4 the handling of this extension
|
|
* has moved down to Cogl. ClutterX11TexturePixmap and
|
|
* ClutterGLXTexturePixmap are now equivalent and either one of them
|
|
* may use the extension if it is possible.
