PNGU v0.1c - linpng for Developer's Released

Back in the Nintendo GameCube days coders were limited to using LibOGC by itself and implementing any few features into their program. Such features would be graphic functions. Well, step in PNGU which is an adaptation of libpng an image processing library for the Nintendo Wii. Using this library you can easily manipulate PNG format files within your homebrew project(s).

Features

* Loads png files from buffer or front SD card.

* Decompress png files and convert them to YCbYCr, RGBA8, 4x4 RGB565, 4x4 RGB5A3 and 4x4 RGBA8 formats.

* Only tested with png files in RGB8 format (but it's probably that works well with others png formats like RGBA8)
