InputDeviceCapabilities would be useful (and should have all
capabilities as @patrickhlauke suggests) - but my guess is with good
defaults less than 5% of developers would use it. If I can pick up
Tilt and use it as is, supported or not (no tilt support means the
stylus is reported as vertical), then I won't look at tiltSupported to
do something special.
With some defaults, InputDeviceCapabilities is required:
opacity = pressure;
if (! InputDeviceCapabilities.pressureSupported) then
opacity *= 2.0; // required to reach 100% opacity on
non-pressure styli
endif
I most often see InputDeviceCapabilities used for displaying settings:
if InputDeviceCapabilities.tangentialPressureSupported then
include UI for wheel settings (wheel changes: opacity, brush size,
spatter density, etc.)
