This package takes the upstream libsquish 1.13,
(https://sourceforge.net/projects/libsquish/) then merges in changes
from all the embedded copies in existing debian packages (as at August
2016).

  - nvidia-texture-tools 1.7 (src/nvtt/squish)
  - 0ad         1.7 (libraries/source/nvtt/src/src/nvtt/squish/)
  - spring      1.10  (rts/lib/squish)
  - openimageio 1.10+ (1.10+metric) (src/dds.imageio/squish)
  - xbmc        1.10+ (1.10+metric/BC45) (lib/libsquish)
  - kodi        1.10+ (1.10+metric/BC45) (tools/depends/native/libsquish-nati$
  - mame        1.13+ (1.13+BC45) (3rdparty/bgfx/3rdparty/libsquish)

These have all been sent upstream, to hopefully be in a 1.14 release
but in the meantime are documented here.
