Added vid_wndalpha to make the window transparent (only supported in GL-win32). Multiple issues with SW rendering, which I'll fix eventually. It does at least run, even if it looks ugly. Plugins are now able to read the console input. Bigfoot, feel free to tweek. Fixed up a few mismatched prototypes. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@3153 fc73d0e0-1445-4013-8a0c-d673dee63da5
