Changes in 1.2.20 (2015-06-26):

* aven:

  + When printing, use the top margin rather than the right margin to calculate
    the height of the printable area.  In practice, the two values seem to be the
    same or very similar by default.

  + Avoid assertion if the about dialog image fails to load.  Reported by Phil
    Maynard.

  + Optimise the size of the about dialog images.

  + Add support for reading terrain data which isn't in a .zip file.

  + Force a refresh after loading terrain data so that it gets displayed right
    away.

  + Make checks for terrain data extensions in zip files case insensitive.

  + If reading terrain data fails, always report an error and never try to
    display it.

* cavern: Allow clino readings in diving style data, suggested by Andrew
  Atkinson.  Currently these readings are ignored, but a future version will
  check that they're consistent with the angle given by the depth gauge and
  tape, and perform suitable averaging.

* Remove lingering traces of svxedit.

* configure: Fix to allow compiling without libav/ffmpeg, as was possible
  before 1.2.19.

* (Unix version): Install the filetype and aven application icons under
  /usr/share/icons/hicolor, which is where they're expected to be these days.

* (Unix version): Add %f to Exec in survex-aven.desktop.

* (Mac OS X version): Remove useless extra copy of about box images from OS X
  disk image.

* (Mac OS X version): Only ship one copy of each of the translations.

* (Mac OS X version): Reduce the size of the aven binary by disabling a load of
  libav features we don't use.

* (Microsoft Windows version): Reduce the size of the aven binary by disabling
  a load of libav features we don't use.

* (Microsoft Windows version): Update message files to fix a missing Chinese
  message in the installer.
