\ Type: Macro

\ 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
