Special case binary symbology for encoding a 32 bit input, with 
optional triangular delimiters at each end.

PostScript integers are 32 signed values so this code contains logic
to avoid numeric overflows when converting the input to a binary 
string.

Available options:

symtype - EMS (default) / BOBST / anything else for custom type
xwidth - width for wide bar for custom symbol type
ywidth - width for spacing for custom symbol type
zwidth - width for narrow bar for custom symbol type
height - set symbol height in mm
width - force symbol to given width in mm
laterallsb, lateralmsb - triangular delimiters
lsbgap, msbgap - width of the space between bar and diemark
inkspread, includetext, textpos, textxpost, textfont, textsize,
showborder, borderwidth, borderleft/right/top/bottom - usual meanings
