Hi,
gtk defines a gtk-dnd-drag-threshold property, and many gtk widgets use it to prevent drag from starting when user moves mouse with a really small movement. This is really important for accessibility (think, ill or old people whose hands shake a lot).
I would be nice if WebKitWebView would not start a drag if gtk_drag_check_threshold returns false.

I've investigated a bit, and discovered Gtk Widget usually make that check in in motion_notify_event callback, and do not call gtk_drag_begin if it's false. But making this check in webkit_web_view_motion_event would prevent all mouse move events, not only drags.

Then, I don't known how to handle that.
