tapToClick option actually not used
There's not really much more to say, it's just that the tapToClick option is not actually used.
The comment right above the condition that checks for the number of pixels moved (line 260) says that the option would be checked here, but that's not true, it's not being checked anywhere, and looking at the previous releases it looks like it was never used
The side effects are click events that are being triggered twice.
