More progress, NEWCLIP added to doomdef.h, sadly it actually all lags the game so I've disabled it for now Other notes: * on second thought I'll keep the hw_clip functions' gld prefixes rather than HWR, not like it matters either way * despite the extra lag it does fix the issues with translucent walls and such when displayed at different vertical angles, such as with the GFZ1 waterfall
