Have a look at https://therion.speleo.sk/wiki/metapost#point_symbols for the re definition of point block. You could probably do something similar with line rock-border (maybe, I have not looked at the rock-border code).

Currently if I have a closed `rock-border` the contents (the rock) will be drawn slightly darker than the passage fill due to transparency and this area being painted twice - see http://filez.foxel.org/e817c23fd65d Is it possible to fill rocks with an other color than the passage fill color?
