\ Garbage.fs
\
\  A compact, simple implementation of a garbage-collected
\  cons-pair heap utilizing Cheney's algorithm.
\  Pointers to pairs are identified by a pattern in the
\  high-order bits of a value, chosen not to collide
\  with the constants "true" or "false".

// 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!
