Description

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.
