Looks good.

Just one more thing regardig the "Version Directive" section,
specifically the portion giving example code for the version 3.8
defaults behaviour:

The revised presentation of the example code gives it the air of three
separate examples, but that's not how it was intended; rather, it was
designed as a single example, intended to demonstrate how the `#version`
directive can (or cannot) switch back and forth between defaults.

As a matter of fact, the third portion of the example wouldn't have the
described effect if used stand-alone - even if the `#default` statement
was moved from the end of the 2nd portion to the beginning of the 3rd one.

Also prediction of tint is easier with 1 as multiplier than with anything else,
plus, it provides one less value shift in the case of bitmapped textured
finishes.
