as the evas internals (and engines internal too) will change, maybe we can wait and just port the opengl engine to windows first I can't these days (work + windows non understandable bugs to hunt), so Hermet, if you can do it, please go. thanks Vincent ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
