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

actually creates it, so it was deemed safe to change.
Some of the old type names differed from the documentation,
