Adopt C99 bool in the printing API.

Browse Source 
Not many changes here: the 'dotted' flag passed to print_line_dotted
is bool, and so is the printing_in_colour flag passed to
print_get_colour. Also ps_init() takes a bool.

line_dotted is also a method in the drawing API structure, but it's
not actually filled in for any non-print-oriented implementation of
that API. So only front ends that do platform-specific _printing_
should need to make a corresponding change. In-tree, for example,
windows.c needed a fix because it prints via Windows GDI, but gtk.c
didn't have to do anything, because its CLI-based printing facility
just delegates to ps.c.

\S{print-line-dotted} \cw{print_line_dotted()}
\c void print_line_dotted(drawing *dr, int dotted);
\c void print_line_dotted(drawing *dr, bool dotted);
This function is called to toggle the drawing of dotted lines during
printing. It is not supported during drawing.
The parameter \cq{dotted} is a boolean; \cw{TRUE} means that future
lines drawn by \cw{draw_line()}, \cw{draw_circle} and
\cw{draw_polygon()} will be dotted, and \cw{FALSE} means that they
will be solid.
Setting \cq{dotted} to \cw{true} means that future lines drawn by
\cw{draw_line()}, \cw{draw_circle} and \cw{draw_polygon()} will be
dotted. Setting it to \cw{false} means that they will be solid.
Some front ends may impose restrictions on the width of dotted
lines. Asking for a dotted line via this front end will override any
