Cut out all of the old texture environment code and rewrote it from
scratch. There were just too many cut-and-paste errors in the code,
and it was too hard to follow.
This fixes Mesa bugzilla #1508. #1509 is probably also fixed, but
I'd like to do some more testing before I close that particular bug.
Additionally, this cuts almost 4,600 lines of code from the driver.
