// This is an input plugin using the XInput 2.0 extension to the X11 protocol,
// loosely based on the old XLib plugin. (Has nothing to do with the XInput
// API on Windows.)
// This plugin creates one KeyboardMouse object for each master pointer/
// keyboard pair. Each KeyboardMouse object exports four types of controls:
// * Mouse button controls: hardcoded at five of them, but could be made to
// support infinitely many mouse buttons in theory; XInput2 has no limit.
// * Mouse cursor controls: one for each cardinal direction. Calculated by
// comparing the absolute position of the mouse pointer on screen to the
// center of the emulator window.
// * Mouse axis controls: one for each cardinal direction. Calculated using
// a running average of relative mouse motion on each axis.
// * Key controls: these correspond to a limited subset of the keyboard
// keys.
// Mouse axis control tuning. Unlike absolute mouse position, relative mouse
// motion data needs to be tweaked and smoothed out a bit to be usable.
// Mouse axis control output is simply divided by this number. In practice,
// that just means you can use a smaller "dead zone" if you bind axis controls
// to a joystick. No real need to make this customizable.
#define MOUSE_AXIS_SENSITIVITY 8.0f
// The mouse axis controls use a weighted running average. Each frame, the new
// value is the average of the old value and the amount of relative mouse
// motion during that frame. The old value is weighted by a ratio of
// MOUSE_AXIS_SMOOTHING:1 compared to the new value. Increasing
// MOUSE_AXIS_SMOOTHING makes the controls smoother, decreasing it makes them
// more responsive. This might be useful as a user-customizable option.
