Mike Erwin 060bf1bd28 OpenGL: draw empties without GLU
Also reduced number of matrix ops by generating final positions directly.

Also removed a display list (deprecated in modern GL).

Tried to reuse sinval & cosval tables but those values are skewed (last value repeats first value, middle values are squished to compensate). Went with sinf & cosf instead.
