Bad default glyph size
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If I open a small model (bounding box edge length about .1) and add vector glyphs of the normals, the "scale factor" changes to 397794.090337098 and hence the arrows are ENORMOUS and it makes the model look like a single point. If I check "Edit", change the scale factor to .1, and hide then show the model (to reset the zoom), it looks correct.
