Adding a progress indicator to the INFO header

Hi,

there is more than one way to signal progress in long running operations but the best looking one, the render progress indicator, is as far as I know not available for reuse.

So I explored some other options and came up with a replacement. It is a bit of a hack but works quite well. The result looks like this:


And in-depth discussion of the code to realize this, is in this article.

Enjoy,
