Make showtris to affect only 3d context
This should exclude 2d. It’s not hard to implement it for r1, i have no clue about r2 yet.
This would help to union multiple debugging outputs together, say drawnotify + showtris, and it would keep console away from the showtris effect.
This mode would be enabled through r_showtris 4 (behaves similar to r_showtris 1) and r_showtris 5 (behaves similar to r_showtris 2) respectively.
Or could be implemented through new cvars:
r_showtris2 1/2 for 2d context (if needed)
r_showtris3 1/2 for 3d context
