[Therion] changing wall line symbol

[Tarquin Wilton-Jones]

Hi Omri,

The usual way that passages are drawn with a background is simply to set
the "color map-bg (93,82,62)" option in your "layout". But that does not
colour an outline of the passage like you have shown.

> the wall line in all the map we made so far looks like this:


What would you want to happen when two passages cross each other? Should
the beige outline go over the lower passage or not?

If it does go over the lower passage, you can probably do it with a new
wall subtype (or redefine the existing ones), using metapost to define
the custom wall line to have a black pen with a coloured pen outline
beside it.

If you want to have the upper passage's beige outline clipped by the
lower passage ... I don't know if that is possible, but I have not seen
a way to do it.

Cheers,

Tarquin
