annotate libinterp/corefcn/gl2ps-renderer.cc @ 20624:4e47e10d5279

Add basic support for multiline and tex markup in printed figures (bugs #31468, 42320, 45301) * gl2ps-renderer.cc (code_to_symbol): new static function. Returns a chararcter in the Symbol font from an utf8 wide char. * gl2ps-renderer.cc (select_font): move code for selecting allowed gl2ps fonts (previously in set_font) in a separate static function. * gl2ps-renderer.cc (escape_character): new static function for escaping postscript special characters such as "(" and ")". * gl2ps-renderer.cc (glps_render::render_text) rewrite function to print parsed strings. * gl2ps-renderer.cc (glps_render::draw_text) use render_text to print parsed strings. * gl2ps-renderer.cc (glps_render::fix_strlist_position): rotate and translate coordinates to align each substring position bottom-left. * gl2ps-renderer.h (glps_render::fix_strlist_position): declare new method
