When the dead zone is a square, it tends to favor horizontal or vertical movement when the joystick position is
nearly aligned with one of the two axis. This makes it more difficult to move at small angles near one of the axes.
The movement tends to snap to the axis.
When the dead zone is a circle, the amount of movement in each axis is in proportion to the angle the joystick
relative to the axes, the movement does not snap to one of the axis and has a more natural feel. The default value
for this setting is for circle (1). If you prefer the action of the original square dead zone instead, the preference can be
set to 0 in the misc tab in the QuadStick Manager Program by turning off the Enable Circular Dead Zone check box.
Certain applications where the outputs controlled by the two joystick axis are not related, may work better with
the square dead zone. This can be controlled on individual mode sheets or on a Preference sheet in a game
configuration spreadsheet.
