Control the size/aspect of the vector and/or cones

[jpsinnecker]

I would like to suggest the developers to add an option/feature in order
to control the size/aspect of the vector/cones. E.g, control of the
size of the vector head and tail, the tail to head relative size, the
number of vectors (one vector every n cells), etc.
Thanks

I've added a number of controls for the vector geometry. They are found in the "Sprite" panel of the preferences dialog. Subsampling has been added (from issue #7) as a menu option with keyboard shortcuts. I'll put this into a 2.1 build in the next day or two!

It works ! Thanks.
