axis source types
Describes the source types for axis events. This indicates to the
client how an axis event was physically generated; a client may
adjust the user interface accordingly. For example, scroll events
from a "finger" source may be in a smooth coordinate space with
kinetic scrolling whereas a "wheel" source may be in discrete steps
of a number of lines.
The "continuous" axis source is a device generating events in a
continuous coordinate space, but using something other than a
finger. One example for this source is button-based scrolling where
the vertical motion of a device is converted to scroll events while
a button is held down.
