Skybox Progress (Patreon)

Skybox mipmapping is complete. Mipmap level can be configured with the d_mipscale_skybox cvar.

The engine upscales truecolor skybox side images to 1024x1024 if lower, and generates mipmaps for all levels down to 128x128. Anisotropic mipmaps are not generated for skyboxes. Skybox mipmaps doesn't use the decontrast filter either. Trilinear texturemapping is also not supported on skyboxes.

Next, I'll implement skybox file saving. This week will likely be busy, but if things goes quick, maybe I'll try to do an unoptimized reimplementation of hybrid skyboxes.
