An attempt to replicate Apple's PNG Mangler.

Apple's PNG files are nowhere near valid (extra critical chunk with an unknown format, zlib headers discarded, premultiplied alpha). "Think different" and all that.

Prerequisites

• a compiler
  • (for iPhone compilation) Apple's Xcode or the open toolchain

Compiling

• iPhone (default target)

    make
  

• Native (linux, OS X)

    make target=native
