Detailed Description

An extension of the KStarsPlotWidget for the AltVsTime tool.

The biggest difference is that in addition to the plot objects, it draws the "ground" below Alt=0 and draws the sky light blue for day times, and black for night times. The transition between day and night is drawn with a gradient, and the position follows the actual sunrise/sunset times of the given date/location. Also, this plot widget provides two time axes (local time along the bottom, and local sideral time along the top).

Version:

1.0

	)			[inline]

Set the fractional positions of the Sunrise and Sunset positions, in units where last midnight was 0.0, and next midnight is 1.0.

i.e., if Sunrise is at 06:00, then we set it as 0.25 in this function. Likewise, if Sunset is at 18:00, then we set it as 0.75 in this function.

Parameters:

	sr	the fractional position of Sunrise
	ss	the fractional position of Sunset
