Most every emote is the same 28x28/56x56/112x112 resolution, except the "basic" faces - R) ;p :p ;) :\ :O B-) O_o :| >( :D :-( :-) and the <3 heart. These, for whatever reason are 24x18/48x36/72x54. This makes for some issues if you're trying to prepare a container for an image before it loads.

Is there any way to include a width/height dimension if the emote's not going to be the standard resolution? Ideally, just in the "https://api.twitch.tv/helix/chat/emotes/global" API call should be sufficient, as (as far as I know) no other emotes have different sizes. However, if there is the possibility of other emotes being non-standard, or if the custom sets (such as the monkeys) have the possibility of variation, then adding the dimensions to the IRC tags for each emote would also be appreciated.

Or, I mean... they could all be resized to match all the other emotes?
