There are two strategies:
1) single server app, all app rendering is accelerated indirect
2) multiple apps - server and apps all use direct rendering

There are plus and minuses to both approaches.

Also note that in a compositing environment app are always drawing to
offscreen buffers - not windows. The server compositing engine is the
only app that touches the scanout buffer.
