Tungsten Graphics Inc. was acquired by VMware Inc. in 2008. Leaving the
old copyright name is creating unnecessary confusion, hence this change.
This was the sed script I used:
$ cat tg2vmw.sed
# Run as:
#
# git reset --hard HEAD && find include scons src -type f -not -name 'sed*' -print0 | xargs -0 sed -i -f tg2vmw.sed
#
# Rename copyrights
s/Tungsten Gra\(ph\|hp\)ics,\? [iI]nc\.\?\(, Cedar Park\)\?\(, Austin\)\?\(, \(Texas\|TX\)\)\?\.\?/VMware, Inc./g
