Serious malfunction in all the spinner controls

[nksauter]

As far as I can see, all the spinner controls are broken in the following sense.
Start the viewer. Single click inside the text box of the Rotation(z) control. Now repeatedly click on the up-arrow.
Even though the value increments, there is no refresh of the picture.

I can't reproduce your problem. Have you also tried with shift-up and shift-down to get the larger scale changes all at once? Are you seeing the "Time taken..." messages indicating the recalculation has happened?

Well, I want to make sure my report was not misinterpreted.

1. Start a new viewer.
2. Single click inside the text box of Rotation (z).
3. Now move the mouse to the up-arrow widget of Rotation (z) and click once. The text box value increases from 0.0 to 0.1, but there is no "Time taken" output, and the picture does not change.

Im having an issue, not sure if its related

1. open sim_view
2. click in the brightness entry box
3. press the left arrow key

instead of moving the cursor within the brightness entry box, it navigates to a new entry box.. Is this expected behavior ?

I believe my latest commit 74e6333 addresses the issue in the title.
