Revert "sc lok: Cache viewdata zoom and reuse for cursor callback"

This reverts fab3c48a for now.
The correct solution is to have the client "hint" at the current
resolution, which is still being developed
(gerrit-id: I34b5afcdcc06a671a8ac92c03e87404e42adf4cd).
For now the cursor will be wrongly positioned when moved as the result
of a mouse click.
