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.
