Hello.
I would like to turn off the render display window while generating .png files for an animation. I have the render options window set to output to a file and not the screen but that appears to only apply when you are rendering a single image.  I am generating over 2,000 .png files as output from an animation and so would like to hide the render visual display window in the hopes that it might save me some level of render time but I don't see where that option is to turn it off.  If anyone knows how to turn it off while rendering an animation please let me know.  Thanks.
