 I've tried to manipulate a font matrix with cairo and failed. This seems
 to be due to that part of the interface being half-finished (text/font
 extents use records, matrices use f64vectors for some reason?), so I
 rewrote it to use records, exposed accessors and
 {{{cairo_get_font_matrix}}}. I've attached a small test program as well
 which exercises this feature set.
