Fixed bug 1672 - Found: seg-fault with testgesture

Browse source 
automata 2012-12-23 22:05:21 PST

An incorrect guard resulted in segmentation faults with the
SDL/test/testgesture executable. The attached patch fixes this issue, and also
allows the program's window to properly handle resize events.

Apply the attached patch to .../SDL/test/testgesture.c
