.Cairo.Font.Matrix (gb.cairo)
Return or set the font matrix.
The font matrix gives a transformation from the design space of the font (in this space, the em-square is 1 unit by 1 unit) to user space.
Normally, a simple scale is used (see
Size), but a more complex font matrix can be used to shear the font or stretch it unequally along the two axes.
