any initialFontName would still need support and the error happens as soon as we 
try to use it in _make_preamble.


Traceback (most recent call last):
   File "C:\code\hg-repos\reportlab\tmp\thello.py", line 21, in <module>
     canv = Canvas('thello.pdf',initialFontName='myfancyfont')
   File "c:\code\reportlab\pdfgen\canvas.py", line 309, in __init__
     self._make_preamble()
   File "c:\code\reportlab\pdfgen\canvas.py", line 401, in _make_preamble
     font = pdfmetrics.getFont(self._fontname)
   File "c:\code\reportlab\pdfbase\pdfmetrics.py", line 673, in getFont
     return findFontAndRegister(fontName)
   File "c:\code\reportlab\pdfbase\pdfmetrics.py", line 655, in findFontAndRegister
     face = getTypeFace(fontName)
   File "c:\code\reportlab\pdfbase\pdfmetrics.py", line 612, in getTypeFace
     return _typefaces[faceName]
KeyError: 'myfancyfont'


if I now run the modified Canvas with


from reportlab.pdfgen.canvas import Canvas
from reportlab.pdfbase.ttfonts import TTFont
from reportlab.pdfbase.pdfmetrics import registerFont, registerFontFamily
registerFont(TTFont('arial','arial.ttf'),)
registerFont(TTFont('arial-bold','arialbd.ttf'),)
registerFont(TTFont('arial-italic','ariali.ttf'),)
registerFont(TTFont('arial-bolditalic','arialbi.ttf'),)
registerFontFamily('arial',
		normal='arial',
		bold='arial-bold',
		italic='arial-italic',
		boldItalic='arial-bolditalic',)
canv = Canvas('thello.pdf',initialFontName='arial')
canv.drawString(72,72,'Hello World')
canv.save()

then the output PDF doesn't contain 'Helvetica'.
