The first FBO we create gets corrupted by something outside
Canvas3D in some cases. E.g. changing the text in an completely unrelated
Text element may corrupt Canvas3D FBOs. This only happens with some GPU
drivers, likely due to a bug in the drivers themselves. To work around
the issue, the first FBO we create is a dummy that we delete once the
real FBOs are done.

There should be no API impact for changing the names of uncreatable
types. ContextAttributes3D is creatable, but most likely nobody
actually creates it, so it was deemed safe to change.
Some of the old type names differed from the documentation,
which is now also fixed as a side effect.

The models were too optimized. Since each face converging at one vertex
could have different texture coordinates, we need to make vertices
of each face unique, so that we can have unique texture coordinates
for each of them. Naturally this increases the rendered vertex count
significantly, but at least the textures are now mapped correctly.
