Yuck. The patches required of TreeVirtual and Table are *fugly*! Some of
the patches appear unnecessary, like patching Scroller, where there are
already nice provided means to do that sort of thing. In this case, you can
provide a function in the 'custom' parameter that instantiates your own
subclass of scroller instead of qx.ui.table.pane.Scrolller, to provide those
additional methods. Are you aware, though, that there can be multiple
scrollers in a single table? Each metacolumn gets its own scroller.
The patching of _onMouseMove looks like something the core team will want to
address, since it indicates that the method is not properly handling what
it's supposed to.
