writing out all transforms in matrices is bad. Having an option to do them
individually is good. If I want to transform a cube, rotate it around the XY
axis 45 degrees and scale it up by 2 in X, down by .5 and up 1.1 in Z, I don't
want to have to sit with a calculator and paper and pencil and figure out the
matrix, I want to say:
transform x y z
rotate axis angle
scale x y z
that seems much more straightforward, especially if we expect "real" people to
use VRML.
