Title: Adds support for limiting the coordinates for stick base.

Adds support for limiting the coordinates for stick base by setting
limitedBase to true providing either a limitMaxX, limitMaxY, limitMinX,
limitMinY, or any combination of the four.

This is very helpful to allow for multiple sticks on the screen, each in a different area of the screen, without having to set the base to a fixed spot.
