3D sceneries

Real-world 3D sceneries for Stellarium! Details: https://stellarium.org/scenery3d.html

Mesa for Windows 20.1.8

MESA3D FOR WINDOWS -- http://mesa.fdossena.com

This library provides software rendering capabilities to OpenGL applications.
Note that software rendering is a LOT slower than 3D accelerators, so this library should only be used as a last resort, with old OpenGL games that won't run on newer hardware.

To use Mesa3D, put the respective version of opengl32sw-{x86,x64}.dll in the same directory as the application executable and rename to just opengl32sw.dll.

This provides a drop-in replacement of Qt's very outdated version of Mesa3D opengl32sw.dll in 32-bit and 64-bit versions.
To be used in CI packaging.
