@mrserb I see where `ToolTipDemoTest.java` uses Jemmy's mouse movement now, thanks. However, since the current implementation is functional and is what the tests are working with, I'd prefer to keep the current implementation of `glide` as is for now.

If the mouse movement used in Jemmy really does turn out to be preferred, we can make a future update to the mouse movement implementation since it does not seem to need any API doc changes. It would be a simple implementation update so I don't see any difficulties with this down the line.
