## Description of change
Game expects primary monitor to be in 90 deg rotation, and does the
touch calculation accordingly.
If the user does 270 deg rotation ("portrait, flipped") then the game's
touch calculation is flipped upside down. Detect this and provide the
fixed up values in the touch hook.
## Testing
Tested with SDVX in 90 deg, 270 deg rotation, and 1080p, forced 1440p.

## 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.
