That is the correct solution.

The way ssgState works (and in retrospect, this may not have been so smart)
is that each attribute (like texture being enabled) has THREE states: Enabled,
Disabled and Don't Care.

By default, everything is Don't Care.  So if you don't explicitly disable
or enable texture, you'll get whatever state was last applied.

This is a good thing for *most* state elements because very often you don't
care what state the graphic pipe is in for many of the states and SSG can
save time by not making lots of redundant state change calls.

Yes.

Yes.
