A variable controlling whether trackpads should be treated as touch
devices.
On macOS (and possibly other platforms in the future), SDL will report
touches on a trackpad as mouse input, which is generally what users expect
from this device; however, these are often actually full multitouch-capable
touch devices, so it might be preferable to some apps to treat them as
such.
The variable can be set to the following values:
- "0": Trackpad will send mouse events. (default)
- "1": Trackpad will send touch events.
This hint should be set before SDL is initialized.
