Pressure sensitive stylus and arc creation

[hilaire]

On Galaxy Note Smartphone, the stylus seems to create multiple events at once when it is pressed on the canvas.
It is a problem to create an arc, angle bisector because it creates immediately two points.

When building Polygon, this problem does not occur.
Likely using the DrGFlyBuildTool and not DrGFlyBuildTouchTool may solve this problem

For the items needing more than two items to be instantiated, we use the DrGFlyBuildTool tool instead of DrGFlyBuildTouchTool:

#createAngleBisector
#createArc
#createArcCenter
