Image Masking with ChimeraText
"""
>>> c = ChimeraText("Sans 12", "test")
Using the fill and stroke parameters you can do things that are

>>> p = Image("../tests/logo.jpg")
>>> c = ChimeraText("Sans 48", "test", fill, stroke="black")
>>> c.show()
Which would stroke the outside of the font in black and fill the
inside of the font with the image
