\ VERTEX x, y, z, face1, face2, face3, face4, visibility
\
\ ------------------------------------------------------------------------------
\
\ Arguments:
\
\ x The vertex's x-coordinate
\
\ y The vertex's y-coordinate
\
\ z The vertex's z-coordinate
\
\ face1 The number of face 1 associated with this vertex
\
\ face2 The number of face 2 associated with this vertex
\
\ face3 The number of face 3 associated with this vertex
\
\ face4 The number of face 4 associated with this vertex
\
\ visibility The visibility distance, beyond which the vertex is not
\ shown

\ Name: EDGE
\ Type: Macro
\ Category: Drawing ships
\ Summary: Macro definition for adding edges to ship blueprints
\ Deep dive: Ship blueprints
\ Drawing ships
\
\ ------------------------------------------------------------------------------
\
\ 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
\
\ visibility The visibility distance, beyond which the edge is not
\ shown
