Only show move/drag button when clipping. Cleanup.

Cleanup:

- remove unused changeViewportMeta function from include/ui.js
- remove some debug output and debug CSS.
- rename panel toggle functions and put them in same location in the
  code.
- refactor some code from updateState to updateVisualState routine
  (renamed from updateSettingsState).
