Description Jakob Petsovits 2013-06-19 07:55:19 PDT 
Discovered by Xuefei Ren.                                                                     
                                                                                                          
If, in rare cases, BackingStorePrivate::renderContents() returns false, the for() loop in render() will take a tile buffer from the surface pool but due to aborting the iteration early, won't put it into the new tile map. In order to prevent losing the buffer, we need to put it back into the surface pool before continuing.

Patch below.
