#X text 160 48 think of this one as a special combination of [#outer]
\, [#] and [#fold]. this is one of the most complex operations. It
is very useful for performing linear transforms like rotations \, scalings
\, shearings \, and some kinds of color remappings. A linear transform
is done by something called matrix multiplication \, which happens
to be [#inner]. [#inner] also does dot product and other funny operations.
