This is a patch to show how we can do a cheap dashed line
for function noodles in geometry nodes.
Using distane between the `P3` and `P0` instead of the real bezier curve
length seems to be fine.
Todos:
If we expose the dash_factor as uniform and have the noodle to use it
depending on whether it is function or data flow I would say this patch
can go to master, and be tweaked later.
Known limitations:
It would be nice to get the "uv.x" to be resampled for the bezier curve
so it is equally distributed in the curve.
Note: To try the patch is recommended to change the theme color for the
Node Editor > Wires. (set it to black)
