# Plug-and-Play fastimagecopyresampled function replaces much slower imagecopyresampled.
# Just include this function and change all "imagecopyresampled" references to "fastimagecopyresampled".
# Typically from 30 to 60 times faster when reducing high resolution images down to thumbnail size using the default quality setting.
# Author: Tim Eckel - Date: 09/07/07 - Version: 1.1 - Project: FreeRingers.net - Freely distributable - These comments must remain.
#
# Optional "quality" parameter (defaults is 3). Fractional values are allowed, for example 1.5. Must be greater than zero.
# Between 0 and 1 = Fast, but mosaic results, closer to 0 increases the mosaic effect.
# 1 = Up to 350 times faster. Poor results, looks very similar to imagecopyresized.
# 2 = Up to 95 times faster. Images appear a little sharp, some prefer this over a quality of 3.
# 3 = Up to 60 times faster. Will give high quality smooth results very close to imagecopyresampled, just faster.
# 4 = Up to 25 times faster. Almost identical to imagecopyresampled for most images.
# 5 = No speedup. Just uses imagecopyresampled, no advantage over imagecopyresampled.
