Feature wishlist

Hi Pier,

Personally, I had the wish for some extra features (do you have a general wish/todo list somewhere?):

• Facet axes spacing/margin options (I wanted tighter custom spacing, per direction customizable).
• Vector/quiver plots (these I use a lot, and I have custom patch function for this now).
• Continuous size scale (also nice together with the vector headsize for example)

The axes spacing and margins seemed to be hardcoded right now, so that one looks quite hard to change.

The vector plots would require an additional input interface, like 'xend' and 'yend' indicating the end of the vectors. Or alternatively you could use a length input 'dx', 'dy'.
