# typebind(window, codes, opts) returns a table of graphic contexts bound to
# window with foreground colors keyed by type in the string of event codes.
#
# Codes for which there is no corresponding color are ignored.
#
# Note: Event monitoring global identifiers must be linked by the program
# that uses this procedure.
