Maybe an added "fit" tag could do it. Where the image is stretched

Of course a single pixel representing a line breaks this, and most
solutions I believe.
I don't think we need to think on this one - what does the spec say?
MapServer bends graphics along a line ... making nice looking roads and
"pipes".
A possibility would be to have the full image, a portion of the image,
or a different image altogether, displayed when the line turns into a
point (because of zooming out). That way when your line shrinks, your
graphic could turn into just an arrow head, instead of an arrow head
plus a line tail. The idea of a line graphic does not work for a point
geometry, because the line graphic is designed for a line. Maybe an
alternate lower-dimentionality image substitute would work.
By arrow Jesse means something like:
____/\____/\_____/\_____/\_____
Rather then:
=======================>
Here let me look it up for you guys:
There are three basic types of strokes: solid-color, GraphicFill
(stipple), and repeated linear GraphicStroke. A repeated linear
graphic is plotted linearly and has its graphic symbol bent around the
curves of the line string, and a graphic fill has the pixels of the
line rendered with a repeating area-fill pattern. If neither a
GraphicFill nor GraphicStroke element is given, then the line
symbolizer will render a solid color.
