With repeated lookups of foreground and background colors for multiple faces per frame, we issue a lot of redundant color name lookups to the X server, waiting every time for the response. On a remote network with, say, 30ms round-trip time, this can add nearly a full second to creation of a new frame. * src/gtkutil.c (xg_check_special_colors): Call x_parse_color. * src/image.c (get_spec_bg_or_alpha_as_argb): (xpm_init_color_cache, xpm_lookup_color): * src/xfns.c (x_defined_color): * src/xterm.c (x_parse_color): New function; caches color names not starting with "#" in the display-info structure. (x_delete_display): Delete the cache content. * src/xterm.h (struct color_name_cache_entry): New type. (x_parse_color): Declare. (struct x_display_info): Add a new field for the cache.
