Preview Range: Show preview range using a different color (based on ANIM_ACTIVE)
instead of using "black" curtains

With most editors now showing the start/end range by default, we need a way of
easily distinguishing when preview range is now enabled. By using a different color
(the exact color used is something we can change/adjust later), there is a more distinct
visual difference between them, making it easier to see what's happening.
