After actually using the above function, I found it was a rather
clumsy fit with:
cairo_set_matrix (cairo_t *cr, cairo_matrix_t *matrix);
Since in the first case cairo_matrix_t is being returned directly as a
value, but in the second it is not. And it seems to me like it would
be a rather bad idea to have cairo_set_matrix accept a cairo_matrix_t
as a value.
So, instead, I've fixed this by putting cairo_get_matrix back like it
looked even before the cairo_matrix_t datatype was exposed:
cairo_get_matrix (cairo_t *cr, cairo_matrix_t *matrix);
Which gives much better symmetry in use.
PS. I'm still mulling over the 3x3 proposals.
