wx backend should not attempt to render jpeg/tiff if PIL is present.

Daniel Hyams · mdboom · commit 2e7399e087d7 · 2013-05-13T13:16:15.000-04:00
If PIL is present, the wx backend needs to allow the base class to get the
job done for print_jpeg and print_tiff, instead of trying to take over
duties itself.
