Avoid many unnecessary allocations, so so that paint engines attached to pixmaps
do not consume excessive amounts of memory, and so can still be reasonably kept
cached with the pixmap.
Saves 8K for every pixmaps drawn to on raster paint engine. Saves about 2K for other graphicssystems.
Task-number: QTBUG-10215
