meta: Don't tweak BaseLevel when doing glGenerateMipmap().
We don't need to worry about levels other than MaxLevel because we're
minifying -- the lower levels (higher detail) won't contribute to the
result. By changing BaseLevel, we forced hardware that doesn't
support BaseLevel != 0 to relayout the texture object.
