[matplotlib-devel] Quiver Patch

[Jordan D. <jdawe@u.washington.edu>]

Ok, here's something of a weird patch, because I don't know how to use 
subversion properly.  It has changes to axes.py which update quiver so 
that it accepts arbitrary X,Y data; it doesn't demand the data be on a 
grid anymore.

The other changes are to collections.py; I updated LineCollection so it 
inherits from ScalarMappable.  I did this just by copying what looked 
like the relevant code from PatchCollection and then I tested it with my 
LineCollection based version of quiver.  I think I got it right, but I 
don't really know what I'm doing here so someone should check it over.
