bug fix png encoder
// by alex evans, 2011. released into the public domain.
// based on a first ever reading of the png spec, it occurs to me that a minimal png encoder should be quite simple.
// this is a first stab - may be buggy! the only external dependency is zlib and some basic typedefs (u32, u8)
//
// VERSION 0.02! now using zlib's crc rather than my own, and avoiding a memcpy and memory scribbler in the old one
// by passing the zero byte at the start of the scanline to zlib first, then the original scanline in place. WIN!
