/**

* Touchscreen gestures API
|
||||
*
|
||||
* A device may implement several touchscreen gestures for use while
|
||||
* the display is turned off, such as drawing alphabets and shapes.
|
||||
* These gestures can be interpreted by userspace to activate certain
|
||||
* actions and launch certain apps, such as to skip music tracks,
|
||||
* to turn on the flashlight, or to launch the camera app.
|
||||
*
|
||||
* This *should always* be supported by the hardware directly.
|
||||
* A lot of recent touch controllers have a firmware option for this.
|
||||
*
|
||||
* This API provides support for enumerating the gestures
|
||||
* supported by the touchscreen.
