//- RF_DEPTHHACK is not like it should be
//- add builtin that sets cl.viewangles instead of reading "input_angles" global
//- finish lines support for R_Polygon***
//- insert selecttraceline into traceline somehow

//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)
