The order of the transformations is important, given in a list
as {R S T} (rotation, scaling and translation).

In the example the point (2,5) is rotated clockwise 45° about
the point (2,2) first, then a translation of 2 in the x-direction
and 6 in the y-direction. There is no scaling, indicated by 11
for the scaling factors.
Rent. No translation gives Tx = Ty = 0 and no
rotation gives 0 = 0.
