For what it's worth, this is the matrix that Gecko produces for
skew(ThetaX, ThetaY):
| 1 tan(ThetaX) 0|
| tan(ThetaY) 1 0|
| 0 0 1|
skewx(theta) is treated as identical to skew(theta, 0) and
skewy(theta) is treated as identical to skew(0, theta).
I have no position on whether this is useful to authors or
mathematically meaningful.
