\
\ The following macro is used to build the ship blueprints:
\
\   EDGE vertex1, vertex2, face1, face2, visibility
\
\ When stored in memory, bytes #2 and #3 contain the vertex numbers multiplied
\ by 4, so we can use them as indices into the heap at XX3 to fetch the screen
\ coordinates for each vertex, as they are stored as four bytes containing two
\ 16-bit numbers (see part 10 of the LL9 routine for details).
\
\ ------------------------------------------------------------------------------
\
\ Arguments:
\
\   vertex1             The number of the vertex at the start of the edge
\
\   vertex1             The number of the vertex at the end of the edge
\
\   face1               The number of face 1 associated with this edge
\
\   face2               The number of face 2 associated with this edge
