Blake Thompson	454326df17	An intial commit of a large set of changes attempting to clean up the way that saving images is processed in image_util.hpp and image_util.cpp. ... * Changed the passing of rgba_palette to a shared_ptr in order to better facilitate the use of a visitor pattern. * Moved PNG util processing into its own set of files so that image_util_impl.hpp would not have to depend on HAVE_PNG.	2015-01-08 10:13:06 -05:00
