Bug 510461

SUMMARY
It 's a good idea to have the Calculator widget resize its width automatically on a side panel when panel width changes. But it becomes odd when it also tend to increase its height very much out of proportion when the vertical space changes, e.g. when the Media Player widget on the same side panel in inactive. 

STEPS TO REPRODUCE
1. Create a panel on the right edge of the screen with a width of 202+ pixels so that the widgets Analog Clock, Calculator, Media Player, and maybe a couple of more will fit in nicely.
2. Change panel width to several different values, for example, between 210 and 250.
3. And finally activate the Media Player by playing an audio or video file using a compatible audio or video player to display album art.

OBSERVED RESULT
The Calculator widget automatically resizes its width to fit into the new panel width, but the way its height is resized is not so smart, trying to take up the entire available empty space without any respect to proportionality.

EXPECTED RESULT
While the Calculator widget size automatically changes according to the panel width, its height should better change within certain minimum and maximum limits, e.g. its height should be no less than 50%, and no more than 200% of its width.
