* @topic Cooking Joystick Data |
*
* We always fetch joystick data raw, then cook it before
* returning it to the application.
*
* If the app is in "raw" mode, then we don't cook anything.
*
* If the app is in "cooked" mode, then things get interesting.
*
* If there is `centered' cooking, then the center point of the
* joystick is reported in the center of the virtual range.
*
*
* Joystick properties work like this:
*
* <c DIPROP_BUFFERSIZE> - No special semantics.
*
* <c DIPROP_CALIBRATIONMODE> - Specifies whether
* cooked or raw data should be returned. If raw data
* is requested, then most other properties have no effect.
*
* The default is cooked.
*
* <c DIPROP_GRANULARITY> - No special semantics.
*
* <c DIPROP_RANGE> - This returns the range of values that
* can be returned by the axis. For joysticks, this is a
* read/write property. (For most devices, it is a read-only
* property.) If you change the property, it affects only
* your device instance; it does not affect the ranges of other
* devices.
*
* If the axis is in calibration mode, then setting this value
* has no immediate effect.
*
* We also define a few new properties:
*
* <c DIPROP_CENTER> - This returns the joystick center (neutral)
* position. In other words, this is the position that
* DirectInput returns when the user has released the joystick
* and allowed it to self-center.
* When a joystick device is created, the center position is
* initially set to midway between the lower and
* upper bounds of the range. An application may change the
* center position (although I don't see any reason why).
*
* If the axis is in calibration mode, then setting this value
* has no immediate effect.
*
* <c DIPROP_DEADZONE> - This returns the size of the joystick
* dead zone, as a percentage of total range.
*
* If the axis is in calibration mode, then setting this value
* has no immediate effect.
*
