They're Boxy But They're Good.

So, what you see here is two separate programs, for no really good reason, with 5 different batches of vertices - one for the triangle, and then four faces of a cube.

Along the way, I migrated to glMatrix.js v2.2.0, which is a comfort. Not a lot necessary at this point to do the migration, so I'm glad I did it when that was true, rather than later, when it would have been a lot of annoying teasing out of weird errors.

Next up, I think, is to pass in the vertex colors into the fragment shaders, as demonstrated in the Learning WebGL Lesson 4. I get what it's doing, so it's just a matter of copying and pasting to get it in, and then tinkering to get it right.

I still intend to break the "model-view matrix" into a "model->world" matrix and "world->camera" matrix. That, too, should be pretty easy.

I've skimmed Lesson 4, and I think I get what's going on. If I understand it, though, it's transforming 3x the vertices necessary and moving down 3x the color information. I'll see if I can get it to run, and then see if I can fix it.
