Since wlroots shaders only use one texture at a time (ie there is only one
sampler2D variable in any shader), it is unnecessary to switch between active
texture units at this time.
Add a signal for wlr_surface destruction on the wlr_surface that compositors
can listen to to remove the surface from their state.
Implement a listener for this in the example wl_compositor to remove the
surface from its internal list of surfaces.
Destroy the surface in the compositor destroy_surface callback given when the
surface resource was created.
Add a reference to the surface resource to the wlr_surface so a compositor can
find it in its list of resources upon wlr_resource destruction.
Implement surface_attach method. This is called when a client attaches an shm
buffer with wl_surface_attach().
Implement the GLES2 interface for attaching shm buffers. This creates an opengl
texture with the shm buffer contents for the surface.
This commit also includes some working code to render the surfaces onto the
screen for demonstration purposes.
Add the wayland surface interface to the example compositor.
Implement the create_surface method to create a new wlr surface from the
wayland surface and add the interface.
The old way of getting the session path was to simply append the session id to
the path "/org/freedesktop/login1/session/". However this is not the correct
path for newer systems like Fedora 26.
Instead, get the session path directly from the session manager from the id via
a dbus call to GetSession().

The previous pixel format (RGBA8888) is not supported on all devices for cursors.
Weston uses ARGB8888 exclusively for its cursor buffer object which leads me to
believe this pixel format is better supported.
