annotate src/video/nanox/SDL_nxvideo.c @ 1718:ed4d4f1ea201 SDL-1.3

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Further progress on the new Windows video driver: * SDL_SetModuleHandle() is obsolete, I hope. * SDL 1.3 uses the UNICODE API * I'm ignoring Windows CE for the moment, we'll reevaluate what needs to be different for Windows CE later. * Pulled the stdio redirection from WinMain()
