Fix compile warnings
Various minor fixes / cleanup.
* Using the Doom-style dome here because it looks better.
* this necessitated changes to the backend to allow both types of sky domes at the same time
* do not clamp panning fields for cloudy sky with the new renderer because this makes the texture jump.
The duplicate 'currentSprite' variable prevented it from doing anything.
Also cleaned up the interface a bit to avoid using a global variable for parameter passing.
