-	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.

+/*
+	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.
