GrannyTextRenderer painters are not properly clipped

[jbfaden]

Annotations with the anchorType plot are clipped within the plot bounds, but I found that any painters used will not be clipped within these bounds. This is because there is a setClip(null) in GrannyTextRenderer:

das2java/dasCoreUtil/src/org/das2/util/GrannyTextRenderer.java

Line 633 in ae056b7

g4.setClip(null);

.

I experimented with leaving the clip alone, but it causes problems with the image painter, at least. This needs to be studied.
