CIRC_RESOLUTION is never used.
Updated default circle resolution and changed name to be more accurate.  Const correctness.  Deprecated arc resolution in favor of circle resolution.
Variable name changes from arc to circle.
Require polyline curves to respect the current path's current `curveResolution`.
Require global curve functions to respect current style's curveResolution.
Updated ofRectRounded.
-Added support for multiple corner radii.
-Use arcs rather than bezier curves.
-Respect for z.
-Respect circleResolution.
Calculate bounding box with new `growToInclude` method in `ofRectangle`.
Unmatched ofPopStyle().
Return values from current style, rather than renderer.
