Key layout patch

[Daniel J S. <dan...@ie...>]

Now would be a good time for me to update some of the patches on S.F. if any of 
the developers are interested.

I think the key-cleanup and enhancement patch(es) is a good one.  I recall there 
being two patches for that.  The first patch was only cleanup, adding no new 
functionality but making the current layout options more robust.  What was good 
about this patch, if I remember correctly, is that it took a step toward making 
plot layout for 2D and 3D similar.

The second patch of this pair was one that added a few more options for laying 
out the key so that it can be placed basically anywhere inside or outside the 
plot borders.

Let me know if you are interested in this one.  Also, should it be kept as two 
different patches?  Or should it be combined into one mondo-patch.

PS:  Is it maybe time to start thinking about a new release?  Developers have 
been diligent about not letting CVS accumulate bugs; this is the time of year 
when most people will have free time; and after only 14 months the release 
process should still be fairly fresh in people's minds.
