Web content refreshes its desired cursor on every mouse event, but
TouchEmulator did not, so the custom "grey circle" touch cursor could
get lost when, say, you move your mouse out of and back into its bounds.

This change make the touch emulator work like web content and refresh
its cursor on every mouse event.
