Function Context.popGroupToSource

The behavior of this function is equivalent to the sequence of operations:

Pattern group = cr.popGroup();
cr.setSource(group);
group.dispose();

but is more convenient as their is no need for a variable to store the short-lived pointer to the pattern.

The Context.popGroup() function calls Context.restore(), (balancing a call to Context.save() by the Context.pushGroup() function), so that any changes to the graphics state will not be visible outside the group.
