Unity Gif Capture

//By Cale Bradbury - netgrind.net
//Toss in Assets/Editor
//Free for any use
//use to slow down unity for capturing frames for external software (gifcam, etc, scrubs only)
//export png sequence to assemble elsewhere (try imagemagick, photoshop)
//protip - right under the game tab there is a drop down where you can pick ratios and set absolute size in pixels.
