QOL: World Building Volume Indicator

[zslayern]

Building Volume Indicator
The construction window now shows the current total building volume on the world and the world's building limit. This appears as a sort of progress control, with a growing strip of city buildings against a blue sky. At 90%, the sky turns yellow. At 99% the sky turns red. The tool tip shows the actual volume numbers.

The indicator is not very obvious, especially if there aren't many buildings on the planet yet.


Could use an outline of sorts to be made more obvious.

To be fair, if there are no buildings on the world, you don't need to see the indicator.

The background of the indicator could be a picture of terrain, so terrain is kinda being replaced by city.
