Share backing canvases between browser compositors.
The software compositor's canvas is only used between BeginPaint and EndPaint. Those happen consecutively for a compositor, so we can share a single buffer to back multiple canvases, one per compositor. This cuts down on memory used to that necessary to contain just the largest window of the process.
