WWT sun path handling

[patudom]

• Having the camera always point at the azimuth of the Sun breaks the view if Sun gets to 90 degrees (because azimuth is undefined). Need to figure out how to smooth the camera view across that hole.
• Need to adjust camera handling for latitudes where sun goes above the altitude that is visible at our set zoom level/camera altitude; or we need to adjust the available zoom level and camera altitude.
• Account for sun taking a northern path even when we're in the northern hemisphere.
• Add a checkbox toggle that lets user "free" the camera so they can do what they want.

If it's easy:

• Add NSEW grid at ~80 deg elevation.
• Make the alt az grid numbers 50% bigger.
• For southern locations, flip orientation of alt az grid numbers and lose the minus sign on the altitudes, and redraw the az grid numbers which we think will get hidden by the horizon and upside down.

Having the camera always point at the azimuth of the Sun breaks the view if Sun gets to 90 degrees (because azimuth is undefined). Need to figure out how to smooth the camera view across that hole.

Can you give me an example of how to reproduce? This feels like something that might be an issue at the WWT level.

Can we leave a trail that has the same color as the season accent color as it moves across the sky, so full path can be viewed on alt/az grid?

It might require a little thought, but I think we should be able to do this. I'm guessing we'd want it to go from some set position (maybe where the Sun rises at the current location) to the current position of the Sun?
