Describes the joystick capabilities.

wPeriodMin, wPeriodMax

Smallest and largest supported polling intervals when the joystick is captured by joySetCapture.

The minimum logical value for each axis is the smallest value that the joystick driver returns for that axis. The maximum logical value for each axis is the greatest value that the joystick driver returns for that axis.
