 The word is actually grab, not grap.

 I think you can add it to any XGrabPointer you want, it is after all the 
purpose of the variable. In the DND case you'll just need to alter the 
nPointerGrabSuccess code to continue even when the grab is avoided, and it's 
also a question if DND can work at all without grabbing the mouse - you'll 
need to try and find out.
