## Description of change
When touch monitors send touch area size information
(`TOUCHEVENTFMASK_CONTACTAREA` flag and `cxContact` / `cyContact` fields
of `TOUCHINPUT` struct) from `GetTouchInputInfo`, IIDX gets confused and
does some unexpected things when interacting with the subscreen.
As a workaround, hook `GetTouchInputInfo` and clear out the flag &
values.
This is only done for IIDX AND when -iidxnativetouch is on.
## Testing
Tested on a Dell touch monitor, simulating "bad" values.
