fteqw/engine/gl/gl_draw.c
Spoike 2adb420a6d Reworked the console/loading screen a little. The console is no longer directly shown at startup. MSVC2005 project files update for npqtv. 
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.
