bd113aa85c transform: Redo querying API
Make the API expect a tranform of the proper category instead of
doing the check ourselves and returning TRUE/FALSE.

The benefit is that the mai use case is switch (transform->category)
statements and in those we know the category and don't need to check
TRUE/FALSE.

Using the wrong matrix will now cause a g_warning().

1fecbd4241 transform: Store the category in the transform
... instead of computing it every time we need it.

This should be faster and we want to use it a lot more prominently.

Also, we have the struct memory available anyway.

3545abc7a1 transform: Implement gsk_transform_invert()
And use it.

And test it.

70b341139b transform: Remove gsk_transform_identity()
This used to be a good idea back when GskTransform was intended to be
used for transitions, but without it, it's not anymore.

cf00c36c85 transform: Split rotate() and rotate3d() class
This is mainly for accuracy: We can guarantee the math we do for 2D
rotations results in a 2D matrix.

3cc84d2860 transform: Make category public API
Also rename it from GskMatrixCategory to GskTransformCategory.

791bf0c2eb transform: Remove API to poke internals
It is not interesting to users of GskTransform how it is made up
internally. Users should just use the gsk_transform_to_*() APIs.

4916280883 transform: Add more API
In particular, add a per-category querying API for the matrix:
- gsk_transform_to_translate()
- gsk_transform_to_affine()
- gsk_transform_to_2d()
- gsk_transform_to_matrix()

This way, code can use the relevant one for the given category.

0e1a50366a transform: Move to GSK
The renaming of the prefix makes this a large patch.
