Add more supported GLSL versions to Wireframe material definition

Resolves #2

[stephengold]

Thanks for your contribution. I ran TestSolidMeshes and pressed the N key a few times to ensure that wireframe materials still work on my system.

1. Would you please run the same test on OpenGL3.2 core profile and report back?
2. I suspect similar changes will be needed for other J3MDs in the Heart library:

• ContrastAdjustment.j3md
• multicolor.j3md
• multicolor2.j3md

(Particularly multicolor2.j3md, since I know MinieExamples uses it.) If I write tests for those J3MDs, would you run them on OpenGL3.2 core profile and report back?

However, I'm a bit confused about the version numbers. Looking around the web I found these mappings between GLSL and OpenGL. But I don't get why GLSL110 (OpenGL2) is not in the list as this is the default JME renderer.

I don't get it either. You might ask @pspeed42.

I added settings.setRenderer(AppSettings.LWJGL_OPENGL32); to the TestSolidMeshes application. I can confirm it is working fine.

(Particularly multicolor2.j3md, since I know MinieExamples uses it.) If I write tests for those J3MDs, would you run them on OpenGL3.2 core profile and report back?

Offcourse, I am glad to help. Let me know when and what I should test.

I'll develop those tests and send you a private message when they're ready.
