13 //- finish player physics code (cs_runplayerphysics)
14 //- EntWasFreed ?
15 //- RF_DEPTHHACK is not like it should be
16 //- add builtin that sets cl.viewangles instead of reading "input_angles" global
17 //- finish lines support for R_Polygon***
18 //- insert selecttraceline into traceline somehow
19
20 //4 feature darkplaces csqc: add builtin to clientside qc for reading triangles of model meshes (useful to orient a ui along a triangle of a model mesh)
