There are three distinct types: XExtensionKeyboard, XExtensionPointer,
and XExtensionDevice.  This comes off the input class, so it's probably

Hmm, it should be fine: you just need to use the device controls to
adjust the pointer feedback control.  The API is pretty terrible, but
it's at least possible, AIUI.
