_1024_GL_CubicCurve Quartz Composer Plugin

Still on the boost this week, so here’s a QC plugin
that might be handy to draw GL Cubic Curves, with handles.
Interpolation step is hardcoded to 40.
10.5/ 10.6, although the included example is 10.6 only,
due to the new Interaction and Instructions patch, so useful for demos.
