feat(render3d): R3D_DRAWSTATS - every draw a frame makes, by pass, program and kind

Browse source 
Measurement only: a tally at each of gpu.ludic's five draw doors, program
changes and texture binds, keyed by the open profiler pass. Off unless
R3D_DRAWSTATS is set; frames byte-identical with it off and on (Mac, OpenGL).
