- Modifications (last one on top):
- 20120830 - WVR: Changed functionality a bit. Now only draw the handles, when the function is drawn.
- Only check mouseMoves, when they occur 'in range'. Redraw the curve, when a resize occurs.
- Somehow, the curve was not drawn correctly, when this was not done (all points were too high).
- After a 'Reset' this would disappear...
- 20120828 - WVR: Removed bSkipText, which was used to not show a number below each vertical gridline.
