Title: ofPath, ofPolyline, ofCairoRenderer :: arcNegative() support added.

All "arc" methods now accept any start or stop angle. Counter clockwise arcs can now be drawn with arcNegative method. Associated Cairo support for "arc_negative" added and tested. Circle Points LUT preserved for all. Arc method generally re-written to support both clockwise and counter-clockwise directions.

This PR fixed to leave out GLUT-keymod-related changes.
