Message:
My understanding of the code is that the if-block cancels emulate3, whereas
the else-block leaves it active.

Message:
The first part of the patch (_abs) seems fine for me.
However I think second part should be:
- if (_abs(threePos.x - pos.x) <= 4 || _abs(threePos.y - pos.y) <= 4) {
+ if (_abs(threePos.x - pos.x) <= 4 && _abs(threePos.y - pos.y) <= 4) {
shouldn't it?
If mouse pointer doesn't move more than 4 points from its original
position (in both X and Y directions), then consider this as "emulate3
press". Otherwise (pointer moved more than 4 points in X or Y or both
directions), don't consider this as "emulate3 press".
