Survex 1.2.8 released

[Olly Betts]

Survex 1.2.8 is now available:

http://survex.com/download.html

Some notable changes are:

 * The export dialog has been reworked - you now select the format
   explicitly rather than it being inferred from the file extension, and
   the options available automatically update to those for the currently
   selected format.

 * You can now export GPX files.  In this release the projection which
   the survey coordinates are in defaults to the BMN M31 grid used in the
   Totes Gebirge in Austria.  On Unix, you can edit ~/.aven and add a new
   line setting 'input_projection' to a PROJ projection string.  The
   ability to specify this projection in a better way is coming soon.

 * Exporting a presentation as a Movie should now work on Windows.

The odd redraw issue some people have reported on Windows seems to
happen less, but is still present.

Here are SHA1 checksums should you want to verify the integrity of the
files:

There's no pre-built version for Mac OS X at the moment - Dan Colish has
been kindly providing these builds, but he no longer has access to a
suitable machine to build them on.

You should be able to build a disk image from source using the
"buildmacosx.sh" script in the source tree - see the comments at the
start of that script for details.

If someone with a Mac is interested in providing builds for others, let
me know.

It would also be good to get the Mac OS X build working with wxWidgets
3.0.0 too.  I'm happy to assist with that if anyone's interested.

There are "release notes" on the wiki, which I'll try to keep updated with any
issues found, so take a look there for the latest information:

http://trac.survex.com/wiki/ReleaseNotes/1.2.8

Please report any issues you find which are not covered in the release notes
to the bug tracker (http://trac.survex.com/).

Cheers,
    Olly

Changes in 1.2.8 (2013-10-29):

* cavern: Fix handling of anonymous wall stations ('..' by default) to
  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
  Holder.

* cavern: Tweak .err file output not to lose the space in front of certain
  statistics when the value gets large.

* cavern: Eliminate redundant progress message when solving simultaneous
  equations.

* aven: Add a format drop down to the export dialog, and only show fields which
  are meaningful and supported for the currently selected export format.  The
  format defaults to that used most recently.  The "Elements" and "View" boxes
  have been swapped in the print and export dialogs as that layout works much
  better when the "View" box is hidden.

* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
  - now works again.  Reported by Anthony Day.

* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
  this release the projection which the survey coordinates are in defaults
  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
  projection string.  The ability to specify this projection in a better
  way is coming soon.

* aven: New export options "Origin in centre" and "Full coordinates" - the
  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".

* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
  time ago, so update references.

* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
  with wxMSW 2.9.5.  Reported by Brian Clipstone.

* aven: Make right click in an empty presentation mark the current position and
  open it to edit, instead of crashing.

* aven: Update movie export code to work with latest libav API.  Reported by
  Sebastian Ramacher.

* aven: Improve reporting of errors during the process of exporting a movie.

* aven: Don't try to close the movie if we aren't producing one.

* aven: Fix assertion failure when double-clicking on the survey with wx2.9.

* aven: Fix to build with wxMSW 2.9.5.

* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.

* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
  ago, so add a new --skencil option to specify this output format.  The old
  name (--sketch) is still recognised for compatibility.

* cad3d: Make --marker-size work for Skencil and SVG output.

* dump3d: Make --show-dates option show dates for XSECT.

* img library:

  + Fix to work once more when used outside of Survex (missing definition of
    max() macro and a bad call to free() in img_close() for a file opened for
    reading).

  + Use lround() instead of round(), and make the tests around whether we use
    the library function or the our fallback implementation saner.

  + Fix // comments in C code for portability to pre-C99 compilers which don't
    support these as an extension.

  + Can now be compiled as C++ as well as as C.

* (Microsoft Windows version): The installer is now built with a newer version
  of Innosetup, and includes translations for all the languages which Survex
  itself has any translations for.

* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.

* Minor translation updates.

* tests/Makefile.am: Distribute files for "normal_bad" testcase.
