Do you have any limits on how many overlays can be drawn? Currently, over 600-700 seem to decrease osd performance in most browsers except firefox alot: (Example: https://gp3.mpg.de/viewer )

@iangilman Sure thing! I might improve it in the future, but if it's helpful to someone as-is, that's great!

@foobarable Yeah, that seems about right. If you want more overlays than that, you might look into using the svg-overlay plugin, or adding and removing the overlays dynamically as the user zooms and pans so there's never more than a few hundred at any one time.
@IllyaMoskvin Okay, added! BTW, if you want it to work in https you can start all your image urls with // rather than http:// (assuming your server supports https)

@iangilman I know, but I still haven't gotten around to allowing https to my server! :P

Fair enough :)
