So, even with the not-working normals, it's starting to look pretty good.
This is the "full" 48,000 basis-tile planet which will have (6?) levels of
subdivision created on an as-needed basis.

Takes about 3+ minutes to automagically create 48,000 infrastructure tiles plus
an additional 48,000 user tiles that will implement all of the user content.

Takes about 6+ minutes to parse it all and render.

I need to do some smoothing of the bicubic patch edges, and start working on the
camera-distance driven subdivision, using a (already written and working) custom
type of specially-modified quad-tree.
And then absolutely filter out everything not in view to keep the memory usage
and parse time way down.

Helpful comments and ideas very very welcome.
