That might do it..

I remember why it doesn't work with fixed pixel sizes now.. the red cue
dot on the end of the line eats the grip when you zoom in to do detailed
work. The line width isn't actually issue unless you're drawing some fat
lines.

In addition, the fixed size swamps the line when you zoom out to do
high-level moves.

FWIW, the current code already has 3 different handle sizes - selected
depending on zoom level.
