Survex 1.2.2 released

[Olly Betts]

I've just uploaded Survex 1.2.2:

http://survex.com/download.html

I'm making this release now as it fixes the annoying assertion failures
when loading certain 3d files, and when viewing passage tubes.  It also
includes a new approach to drawing text on the survey window, and fixes
some issues with the print dialog box.

There's no Mac OS X build of this version yet.  If you want to build your own,
see the instructions at: http://survex.com/download.html?platform=macosx

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

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/1.2.2

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

Changes in 1.2.2 (2011-10-06):

* aven:

  + Replace the textured-mapped font drawing with an approach based on
    glBitmap.  This doesn't suffer from the character alignment issues which
    the textured-mapped fonts had, and is actually significantly faster on some
    machines.  The current font used is (mostly) fixed-width, but this isn't an
    inherent limitation - it was just the easiest font data to convert to a
    usable format.

  + Fix assertion failure due to rounding differences on loading certain .3d
    files.  (ticket#26)

  + Fix assertion failure when turning on 3D passages if they stick out higher
    or lower than any station.  (ticket#29)

  + Fix grid not to disappear when blobs are turned on and blobs are drawn
    using lines.

  + If a degree sign isn't available in the character set in use, transliterate
    it to 'dg' rather than skipping it.

  + Fix message which should have been a degree sign but got lost in the format
    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
    that bearings in the status bar now have a degree sign after them if they
    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).

  + Fix print dialog to calculate the scale required for "One page" right
    before it calculates how many pages are required, so we don't end up
    something other than 1x1 being shown when the user changes settings.

  + Update the calculations for picking a scale and for deciding how many
    pages are needed to take into account the change in info box height made
    in 1.2.1.

Cheers,
    Olly
