Because you don't *have* an OpenGL vendor until you
have a context. Contexts belonging to different
display devices can be using drivers from different
vendors, so it's a property of the context rather
than something global.

Something it's easy to overlook about OpenGL is
that it's really an object-oriented system, with
almost all of the functions being methods of the
context. But the API does a good job of hiding this
by making the current context an implicit global
parameter.
