gEDA-user: pcb: visual indication for locked elements

[Bert Timmerman <bert.timmerman@xxxxxxxxx>]

Hi all,

I thought it would be nice to have a (visual) indication in pcb that a
component is locked.

A way for (visual) indication of locked components is to change
the "diamond" marker (indicating the insertion point) by adding a "L" on
top of it.

It's a trivial amount of lines added to draw.c in DrawEMark ().

Just append at the end of the function.

Patch attached (created with git).

Kind regards,

Bert Timmerman.

Subject: [PATCH] modified:   pcb/src/draw.c
This patch is to allow for locked elements to be recognised on an instant.

If an element is locked an "L" is placed on top of the "diamond" marker.
