Glyphs: Scale only the arrow length instead of the whole glyph size

The glyph filter has the nice property which allows to scale the glyph. However, for all arrow glyphs, a better way of scaling would be to scale only the length of the arrow by a quantity instead of the whole arrow (shaft and tip thickness). This simply gives a much clearer overview if there are regions with big and small arrows in one domain.

Code for the feature: GitHub - nooj/ArrowGlyph: generalization of the ParaView Glyph filter for arrows; allows independent resizing of tip and shaft
