The gsk:transform structure is a structure to describe transform matrices. Unlike the graphene:matrix-t structure, the gsk:transform structure retains the steps in how a transform was constructed, and allows inspecting them. It is modeled after the way CSS describes transforms.

The gsk:transform instances are immutable and cannot be changed after creation. This means code can safely expose them as properties of objects without having to worry about others changing them.
