- Fix for "Wrong mouse position after screen-resize" bug reported here (http://forum.ultra-star.de/viewtopic.php?f=65&t=7768&p=57151#p57151)
- Note: Screen.w and Screen.h are not updated after a resize as SDL_SetVideoMode is not called on windows on a resize event. Previously SDL_SetVideoMode invalidated all OpenGL textures resulting in most textures white. Using SDL_SetVideoMode at a resize seems to work now at least with SDL 1.2.14 and Win7. Maybe we should switch it on again. git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@2328 b956fd51-792f-4845-bead-9b4dfca2ff2c
