Write with NSFileWrapper vs. copy with NSFileManager

GIF frame duration

I'm working with GIF animations. To find out the delay between frames, there's NSBitmap's -valueForProperty: with a value of NSImageCurrentFrameDuration. I.e. [bitmap valueForProperty:NSImageCurrentFrameDuration] should report the delay time for the current frame. Now what I'm seeing is AppKit

Looking at the open source CFXMLCreateStringByUnescapingEntities(), I’d say the code was written to an unrealistic deadline and never reviewed. They scan through the string, looking for the '&', then the ‘#', then the digits, and finally scan past the ‘;' up to the end of the string if necessar
