Compatibility modes uploaded

At the request of one of my downloaders, I also added 2 uploads compiled with Godot's compatibility mode, i.e. using OpenGL 2. People often use older computers to test untrusted content (like .exe files from a website) with.

In this case only compatibility mode was supported by the older device.

Differences

The game works fine, but there are some differences I need to stress, as illustrated in these side-by-side screenshots:

On the left hand side you see the game compiled in Compatibility mode. The right hand side uses Forward+.

As you can see, the transparency of the SubViewport only works in the Forward+ mode. The lighting is also quite different, making the compatible version look like the Sahara desert.

Any advice on how to fix these differences is of course more than welcome!
