Subject: [PATCH] Don't destroy clipping region if empty clipping region is
 required (wxDC, GTK).

For compatibility with wxGCDC (Cairo and all native MSW renderers) current clipping region shouldn't be explicitly destroyed if empty clipping region is requested. It should be handled as any other region.
