Three SIXEL improvements from nincsnevem662 at gmail dot com in GitHub issue

Browse Source 
4149:

- Pass P2 on the received image through when forwarding the image to the
  outside terminal to preserve transparency;

- Preserve raster attribute dimensions which may be smaller than the actual
  image (used to crop out parts of the image to work around the limitation that
  rows must come in groups of six);

- To avoid collapsing empty sixel lines, no longer ignore duplicate "-" new
  line specifiers.
