Context.setFontMatrix

Sets the current font matrix to 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 cairo_set_font_size()), but a more complex font matrix can be used to shear the font or stretch it unequally along the two axes Since 1.0
