I noticed three errors in packages/cairo/CairoTransform.st:

- a typo 'asMatrixTrasform'

- #about: applies the translations in the wrong order

- the lazy instantiation in #asMatrixTransform was predicated on "isNil
ifFalse" rather than "isNil ifTrue"

These may well have been in the source as originally supplied.  In any
case, here's a patch.
