+//               respected, false if it will be ignored.  If this
+//               returns false, then get_pixel_factor() will always

+//
+//               This may return false if the underlying renderer
+//               doesn't support pixel zooming, or if you have called
+//               this on a DisplayRegion that doesn't have both
