Pass back x/y of click in Absolute move subscriptions

[evilC]

Both button and move data can be present in mouse updates, especially in Absolute mode.
At the moment, when a click happens, the coordinates of that click are never passed back via a callback, because State is first checked, and if non-zero, movement is never processed.

Two solutions seem possible:

1. Move to passing a more stroke-like object instead of just state or x/y
2. Remove the ELSE clauses from the checks in the mouse processing loop, and process movement before clicks.
