dev: - add documentation - main() is more readable fix: - unmanaged errors: - map parsing: error if color value is >255 - map parsing: load_textures(): check return value of xml_xpm_file_to_image() - main.c: draw_screen(): check return value of mlx_new_image() other details: - dev: color_from_rgb(): change signature - fix: nullize map in map_destroy - change: change error message for read_all_text() errors - change: change rotation speed - change: add and use contant NOOBONUS_SPEED
