Get joystick position.

Returns the actual joystick position (of selected axes via corresponding boolean doX...Z)

Parameters:

	doX	: TRUE: get X position and modify the *X value. FALSE: Do not modify *X.
	doY	: TRUE: get Y position and modify the *Y value. FALSE: Do not modify *Y.
	doZ	: TRUE: get Z position and modify the *Z value. FALSE: Do not modify *Z.
	doR	: TRUE: get R position and modify the *R value. FALSE: Do not modify *R.
	*X	: Adress of the X value to be modified or not.
	*Y	: Adress of the Y value to be modified or not.
	*Z	: Adress of the Z value to be modified or not.
	*R	: Adress of the R value to be modified or not.
