It depends on your drawing API. If you're using EGL you can use
native pixmaps (wl_egl_pixmap) or you can use pbuffers. Within
GL/GLES2, you can create a texture or a renderbuffer and render to
those using an FBO. Or create a wl_egl_pixmap, create a EGL image
from it and use that with an FBO.

The buffer for a window is only accessible to the client and the compositor.
