	- Fix bugs in gvpr and gv.cpp so edges can be created in subgraphs.
	- Add edgepaint program for coloring edges to make them easier to tell apart.

	- Fix swig java package to work and support gv.renderresult.
	- Fix test for the absence of layout (old test relied on statically allocated \ 
Agraphinfo_t).

	- The fixedsize attribute now takes the value "shape" which allows \ 
labels much larger than the
