Fixed bug 1682 - Resize collapses window instantly to a size of 0 x 124.

Marco Schmidt After sizing my main window (the only window in my application) through grabbing the window border with the mouse the window collapses instantly to a size of 0 x 124. In my application I can not resize the window to a normal size again. I tried to reproduce the problem - and here a the minimal steps I found. I'm running WIN8 x64, VS2012Pro, HG SDL-2.0 tip, WIN32-Build. Minimal steps to reproduce my problem: - open solution SDL_VS2012 - make testdraw2 the start project - pass command line option --resize to the debuggee testdraw2 - starting the application testdraw2 - try to resize the window - the application window resizes to a minimal size 0 x 124. - the application crashes to divide by zero .... (this is only the aftermath but a unhandled error condition)
