Build intersect.exe on Visual Studio 2022

[phil-martin-situ]

At the moment the built in solution file and projects don't build with VS 2022.

There's two parts to this:

• Building the the intersect and related projects
• Building the GLUT related projects.

This issue is just about building the intersect.exe.

All the errors are to do with symbols or header files having changed over the years.
