Context.getScaledFont

the current scaled font. This object is owned by cairo. To keep a reference to it, you must call cairo.scaled_font.ScaledFont.reference.

This function never returns null. If memory cannot be allocated, a special "nil" #cairo_scaled_font_t object will be returned on which cairo.scaled_font.ScaledFont.status returns cairo.types.Status.NoMemory. Using this nil object will cause its error state to propagate to other objects it is passed to, (for example, calling cairo.context.Context.setScaledFont with a nil font will trigger an error that will shutdown the #cairo_t object).
