    Avoid cairo_show_text(), use PangoLayout instead
    
    The cairo context might not have set correct font, which could break
    drawing of event times for some locales, like te_IN. Using the PangoLayout
    also sets the right font and makes it work properly. Interestingly
    only these two places used cairo_show_text().
