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!
//
// more context at http://altdevblogaday.org/2011/04/06/a-smaller-jpg-encoder/.

float->sRGB8 using SSE2 (and a table)
// float->sRGB8 conversions - two variants.
// by Fabian "ryg" Giesen
//
// I hereby place this code in the public domain.
//
// Both variants come with absolute error bounds and a reversibility and monotonicity
// guarantee (see test driver code below). They should pass D3D10 conformance testing
// (not that you can verify this, but still). They are verified against a clean reference
// implementation provided below, and the test driver checks all floats exhaustively.
