Describe the bug
Check asciinema/asciinema-player#52

To Reproduce
Steps to reproduce the behavior:

1. Run the script and covert it to gif:

#!/bin/bash

printf "\n"
printf "    _   __                           __   \e[2m______      _       __ \e[0m\n"
printf "   / | / /___  _________ ___  ____ _/ /  \e[2m/ ____/___ _(_)___  / /_\e[0m\n"
printf "  /  |/ / __ \/ ___/ __ ´__ \/ __ ´/ /  \e[2m/ /_  / __ ´/ / __ \/ __/\e[0m\n"
printf " / /|  / /_/ / /  / / / / / / /_/ / /  \e[2m/ __/ / /_/ / / / / / /_  \e[0m\n"
printf "/_/ |_/\____/_/  /_/ /_/ /_/\__,_/_/  \e[2m/_/    \__,_/_/_/ /_/\__/  \e[0m\n"
printf "\n"

Expected behavior
The gif works same as asciinema player.

Thanks. Faint attr support is missing indeed, but should be rather straightforward to add it.
