* `category >= GSK_TRANSFORM_CATEGORY_2D` is the way to do this.
|
|
*
|
|
* Also keep in mind that rounding errors may cause matrices to not
|
|
* conform to their categories. Otherwise, matrix operations done via
|
|
* mutliplication will not worsen categories. So for the matrix
|
|
* multiplication `C = A * B`, `category(C) = MIN (category(A), category(B))`.
