Converts a `GskTransform` to 2D transformation factors.
To recreate an equivalent transform from the factors returned by this function, use
gsk_transform_skew ( gsk_transform_scale ( gsk_transform_rotate ( gsk_transform_translate (NULL, &GRAPHENE_POINT_T (dx, dy)), angle), scale_x, scale_y), skew_x, skew_y)
this must be a 2D transformation. If you are not sure, use
get_category >= gsk_transform_category_2d
to check.
