// This bit is important.  It detects/adds XMLHttpRequest.sendAsBinary.  Without this
// you cannot send image data as part of a multipart/form-data encoded request from
// Javascript.  This implementation depends on Uint8Array, so if the browser doesn't
// support either XMLHttpRequest.sendAsBinary or Uint8Array, then you will need to
// find yet another way to implement this. (This is left as an exercise for the reader,
// but if you do it, please let me know and I'll integrate it.)
