Spoike 22bb395305 hexen2 client effects now go via the particle system, if they're supported at all. Added 'h2part' description to provide this. 
Fixed svc_setangles and sv_bigcoords.
Model code is now responsible for transforming traces instead of it being generic. This fixes rotating things getting stuck in players in hexen2.
The renderer now generates a list of surfaces to draw. Backend now performs rotations/scaling per entity. This fixes sorting order, at least when not using realtime lights.
Hidden items in the hexen2 inventory that you do not have.
Added colourmapping for hexen2.
Should be easier to click on menu items for hexen2.
