celestial accurate sun and moon cycles

The sunset color has been changed, hopefully for the last time. Previously, there was a problem that the lighting was too dark at dusk, and it was too bright during the daytime part of sunset. The algorithm for rendering the direction of twilight for the sun has been changed. Specifically, accuracy has been improved at polar latitudes or at extreme values of the inclination of the Earth's orbit during noon or midnight. The following textures have been changed:

• the sun. Its resolution has become 500 pixels instead of 110 pixels in thickness.
• Mercury. Before that, its texture was crookedly inserted.
• Venus. Before that, there was a square around Venus, approximately blue in color, which was different from the main sky
• Moon. The background was removed, which created inaccuracies in the lighting, and the "misty area" became more consistent. Previously, the invisible part of the moon was drawn randomly with the first color that came to mind. Now, each phase has a strict brightness law based on the lighting conditions. For example, in the thin phases of the moon, the unfilled part is clearly visible due to the reflection of light from the Earth, as the Earth has a nearly full phase for the moon at that time. !subtle waxing cresent 6,7%
