r600 double sky effect looks different.

Not sure if this is intentional or not because I know that the sky drawing code has been tweaked recently but the quake-style double sky effect seems to have changed. Specifically, the front clouds graphic in the attached example seems shorter (top to bottom) than it did before.

The aim of the change was to bring sky stretching more in line with the aspect in the software renderer, so this outcome is not what's intended.

Fixed. The recent changes exposed a bug in the sky code that has always been there but until now never showed in an obvious way.
