Sets the source pattern within cr to source. This pattern will
then be used for any subsequent drawing operation until
a new source pattern is set.
Note: The pattern's transformation matrix will be locked to
the user space in effect at the time of setSource(). This
means that further modifications of the current transformation
matrix will not affect the source pattern.
See Pattern.setMatrix().
The default source pattern is a solid pattern that is opaque
black, (that is, it is equivalent
to setSourceRGB(0.0, 0.0, 0.0)).
