Look into porting DrawRotatedPic from etlegacy.

Make sure that a cgame with this extra syscall would still work on older clients, and see if a none rotated pic can be used as a fallback for old clients. If that works, fully port this feature, it would be useful for things like minimaps.

Hi,
I answer you immediately to say that you should import it from unvanquished. A contact already do this.
However this person only do it for personal purposes, and I don't think that I could get his sources, but he affirmate (~3-5 years ago) that he just copy it from Unvanquished.
Just want to indicate a possible fine way to do it.
Probably it will support old client finely by default.

Thanks @Buom01 :) , I'll compare between etlegacy and Unv, not sure if there would be a significant difference for the rotating of pictures feature specifically, etlegacy's render code in general would be closer to trem's renderer code though. I did previously start to look into porting the overall minimap system from Unv.
