Re #1327, some fixes on the simple GUI app:

  • Removed timer usage in resizing window, window resizing can be done real-time now (see r3698).
  • Fixed linking problem on Windows platform: undefined 'main' function.
  • Fixed build problem on Mac, compiling .cpp file containing objective C/C++ codes with g++ needs '-ObjC++' flag.
  • Minor changes in vidgui, e.g: function/variable rename, cleaning up unused/junk lines.
