== DETAILS
Apparently when I refactored this code, I missed out on the fix for
touchpad coordinates that @QuarkTheAwesome had committed.
Oops.
- Fix the touchpad coordinates
- Remove unneeded references to video driver in wpad_driver.c
- Remove unneeded video driver include in pad_driver.h
- Add logging in wpad_driver to verify the fix (#ifdef'd out by default)
== TESTING
Verified fix manually.
