- core: add support for using StelProjector::unProject analogue in shaders
- core: render Milky Way calculating view direction per fragment
- core: render Zodiacal light calculating view direction per fragment
- core: don’t try to render a Planet whose textures are not all loaded
- core: load Planet textures synchronously
