Running Principia on obscure platforms

Now that Principia is an open source project, you can build it from source to target any device possible within our supported platforms, or port it to a new platform.

A while ago I ported Principia to Haiku OS. The support code is still in the main repository and there's a link to the compilation instructions on the download page, but I haven't tested if it still works in a while.

As Haiku OS supports OpenGL and has GTK3 available, the port is more or less fully features, barring some minor platform-specific code that hasn't been implemented and would need someone more familiar with Haiku OS to implement.
