The the following is taken from
4415175: New API to Globally Change the DnD Gesture Motion Threshold
The drag motion gesture threshold represents the number of pixels the cursor is dragged before the data transfer system initiates a drag operation. Prior to this release, this was hard-coded to 5 pixels. As of release 5.0, there is support for picking up the desktop properties for drag sensitivity and mapping it to the threshold, and new API that allows users to get and change this threshold. The new API includes:
d (a property)
zer (updated class spec)
How can I change the drag sensitivity? Im unsure how to implement the above.
