Fix SHM drawing logic
The old logic didn't care to listen for wl_buffer.release events so it always drew in the same buffer, potentially resulting in tearing if the compositor was scanning out the buffer at the same time. Instead properly cycle between a few buffers and don't reuse the same one until the release event was received. The old code also used to throttle the redraws, unless the buffer was changing, that is unless the window was getting resized. This is now lost, and no throttling is ever done. Doing it properly, by waiting for the frame callback before committing the new buffer shows very noticeable lags with many applications when resizing, because they paint many times per resize event, so they fall behind the cursor. A proper fix will be to implement the support for requestUpdate(), and using it in the applications.
