Survex 1.4.12 released

[Olly Betts]

Survex 1.4.12 is now available:

https://survex.com/download.html

It seems appropriate to dedicate this release to the memory of Andy
Waddington (aka Wadders) who died fairly recently.  His !Survey cave
survey software for RISC OS was one of the early inspirations for
Survex.  We didn't go with his proposal to call it the Betts Underground
Mapping System though.

Here's the full NEWS file entry for this release:

Changes in 1.4.12 (2024-10-23):

* aven:

  + (Microsoft Windows version): Geodata overlays are (hopefully temporarily)
    no longer available in the pre-built version of Survex installed by the
    Microsoft Windows installer.  We use the GDAL library to load them and
    there's a hard to debug problem during DLL initialisation somewhere in its
    dependency tree.  If you really need geodata overlays, the 1.4.9 installer
    still works.  Thanks to Wookey for extensive testing to investigate the
    problem, and to everyone else who reported this.

* cavern:

  + A leg with the same station as from and to is now only a warning in
    Compass data.  Compass itself seems to quietly ignore such legs, but
    they seem worth warning about.  In native Survex data this is still
    an error.

  + Short survey and station names are now stored without an extra memory
    allocation.  On a 64-bit platform (most modern computers) we can store
    name components up to 7 characters in this way; on a 32-bit platform
    up to 3 characters.  On a large dataset which needs large matrices
    solving this reduces cavern's memory usage by 3.5MB (~4.5%).  It's
    also fractionally faster (but only ~0.05% which is not normally even
    measurable).

  + Assigning matrix row numbers to stations is now faster and allocates
    less memory.

* (Microsoft Windows version): The Microsoft Windows installer is now
  named `survex-microsoft-windows-1.4.12.exe`.  The old name was
  `survex-win32-1.4.11.exe` but the "win32" is now misleading as it's been a
  64-bit build since 1.4.9.  Reported by Wookey.

* Testsuite:

  + dump3d.tst: Add tests of img library's survey filtering.

  + cavern.tst: Normalise `-0.00` to `0.00` in JSON test output before
    comparing with expected output.  We can get -0.00 on x86 due to excess
    precision.

* img library:

  + Survey filtering now works correctly for files which use a survey level
    separator other than `.`.  Patch https://github.com/ojwb/survex/pull/14
    from Thomas Holder.

  + Reading a v7 or earlier .3d format extended elevation with survey filtering
    was failing to set is_extended_elevation.
