// Paramters:
$parameters = [];

// Area             - Valid tablet area in device coordinates. 
// Button           - X11 event to which the given button should be mapped. 
// ToolDebugLevel   - Level of debugging trace for individual tools (default is 0 [off]). 
// TabletDebugLevel - Level of debugging statements applied to shared code paths between all tools associated with the same tablet (default is 0 [off]). 
// Suppress         - Number of points trimmed (default is 2). 
// RawSample        - Number of raw data used to filter the points (default is 4). 
// PressureCurve    - Bezier curve for pressure (default is 0 0 100 100 [linear]). 
// Mode             - Switches cursor movement mode (default is absolute). 
// TabletPCButton   - Turns on/off Tablet PC buttons (default is off for regular tablets, on for Tablet PC). 
// Touch            - Turns on/off Touch events (default is on). 
// HWTouchSwitchState - Touch events turned on/off by hardware switch. 
// Gesture          - Turns on/off multi-touch gesture events (default is on). 
// ZoomDistance     - Minimum distance for a zoom gesture (default is 50). 
// ScrollDistance   - Minimum motion before sending a scroll gesture (default is 20). 
// TapTime          - Minimum time between taps for a right click (default is 250). 
// CursorProximity  - Sets cursor distance for proximity-out in distance from the tablet (default is 10 for Intuos series, 42 for Graphire series). 
// Rotate           - Sets the rotation of the tablet. Values = none, cw, ccw, half (default is none). 
// RelWheelUp       - X11 event to which relative wheel up should be mapped. 
// RelWheelDown     - X11 event to which relative wheel down should be mapped. 
// AbsWheelUp       - X11 event to which absolute wheel up should be mapped. 
// AbsWheelDown     - X11 event to which absolute wheel down should be mapped. 
// AbsWheel2Up      - X11 event to which absolute wheel up should be mapped. 
// AbsWheel2Down    - X11 event to which absolute wheel down should be mapped. 
// StripLeftUp      - X11 event to which left strip up should be mapped. 
// StripLeftDown    - X11 event to which left strip down should be mapped. 
// StripRightUp     - X11 event to which right strip up should be mapped. 
// StripRightDown   - X11 event to which right strip down should be mapped. 
// Threshold        - Sets tip/eraser pressure threshold (default is 27). 
// ResetArea        - Resets the bounding coordinates to default in tablet units. 
// ToolType         - Returns the tool type of the associated device. 
// ToolSerial       - Returns the serial number of the current device in proximity.
// ToolID           - Returns the tool ID of the current tool in proximity.
// ToolSerialPrevious - Returns the serial number of the previous device in proximity.
// BindToSerial     - Binds this device to the serial number.
// TabletID         - Returns the tablet ID of the associated device. 
// PressureRecalibration - Turns on/off Tablet pressure recalibration
// PanScrollThreshold - Adjusts distance required for pan actions to generate a scroll event
// MapToOutput      - Map the device to the given output. 
// all              - Get value for all parameters.
