Been a while, apologies :) Added: * Direct: fg_palindex (`ncdirect_fg_palindex`) * Direct: bg_palindex (`ncdirect_bg_palindex`) * Direct: get_palette_size (`ncdirect_palette_size`) * Direct: putstr (`ncdirect_putstr`) * Direct: hline_interp (`ncdirect_hline_interp`) * Direct: vline_interp (`ncdirect_vline_interp`) * Direct: box (`ncdirect_box`) * Direct: rounded_box (`ncdirect_rounded_box`) * Direct: double_box (`ncdirect_double_box`) * Direct: canopen_images (`ncdirect_canopen_images`) * Direct: canutf8 (`ncdirect_canutf8`) * Menu: get_mouse_selected (`ncmenu_mouse_selected`) * NotCurses: version_components (`notcurses_version_components`) * NotCurses: str_blitter (`notcurses_str_blitter`) * NotCurses: str_scalemode (`notcurses_str_scalemode`) * NotCurses: lex_margins (`notcurses_lex_margins`) * NotCurses: lex_blitter (`notcurses_lex_blitter`) * NotCurses: lex_scalemode (`notcurses_lex_scalemode`) * NotCurses: render_to_file (`notcurses_render_to_file`) * Plane: putstr_stainable (`ncplane_putstr_stainable`) * Plane: printf_stainable (`ncplane_printf_stainable`) * Plane: vprintf_stainable (`ncplane_vprintf_stainable`) * Reel: offer_input (`ncreel_offer_input`) Changed: * Direct: set_fg_alpha uses `unsigned alpha` * Direct: set_bg_alpha uses `unsigned alpha` * Plane: set_fg_alpha uses `unsigned alpha` * Plane: set_bg_alpha uses `unsigned alpha` * Root: made `error_guard` and `error_guard_cond` static
