use the addMapping function to tell the library that these 4 fonts
form a family e.g.
from reportlab.lib.fonts import addMapping
addMapping('Vera', 0, 0, 'Vera') #normal
addMapping('Vera', 0, 1, 'Vera-Italic') #italic
addMapping('Vera', 1, 0, 'Vera-Bold') #bold
addMapping('Vera', 1, 1, 'Vera-BoldItalic') #italic and bold
