# Main chroma function. It allows to create the command-dedicated chromas
# (like -git.ch) through a definition provided by `chroma_def' array (read
# from the upper scope).
#
# $1 - 0 or 1, denoting if it's first call to the chroma, or following one
# $2 - the current token, also accessible by $__arg from the above scope -
#      basically a private copy of $__arg
# $3 - a private copy of $_start_pos, i.e. the position of the token in the
#      command line buffer, used to add region_highlight entry (see man),
#      because Zsh colorizes by *ranges* in command line buffer
# $4 - a private copy of $_end_pos from the above scope
#
