// USAGE:
// call stb_compress_dxt_block() for every block (you must pad)
// source should be a 4x4 block of RGBA data in row-major order;
// A is ignored if you specify alpha=0; you can turn on dithering
// and "high quality" using mode.
// Alpha channel is not stored if you specify alpha=0 (but you
// must supply some constant alpha in the alpha channel).
// You can turn on dithering and "high quality" using mode.
//
// version history:
// v1.08 - (sbt) fix bug in dxt-with-alpha block
