Update "xlockmore" package to version 5.28. Changes since 5.27:
- invert: build failures from Sun Studio Express C++ like this:
    Error, manymatchover: Overloading ambiguity between "operator^(const
    TwoJet, double)" and "built-in operator^(int, int)" fixed by \ 
casting
    to double, thanks to Tim Mooney <Tim.Mooney AT ndsu.edu>.
- life3d:
    4 more rhombic dodecahedron S3/B3 patterns including a period 4 pattern
      (only S3/B3 period 2 and less patterns left from Bays' papers).
    Glider code revamped to make more maintainable, using populateGlider().
    unsigned int fix thanks to Jouk Jansen.
    Added new cube gliders from Bays 2006 3D Life paper and found a few
      patterns for the gliders to crash into.  (S23B5, S25B5, S27B5, S35B5,
      S36B5, S37B5, S38B5, S4B5, S47B5, S57B6, S58B5, S8B5).
    New mode option added "+draw", this turns off drawing to the screen
      to speed up searches, and more importantly, make less annoying :)
- life: resyncing with my Java code.
    Switched how static triangular forms are stored
    Added a lots of new triangular patterns, including 2 gunship triangular
      patterns.  Also added handful of other patterns.
    Reading memory on uninitialized variables fix thanks to Jouk Jansen.
    "+draw" mode option added.
    Pentagonal (Cairo Tiling) life added with glider shooters.
      "xlock -mode life -rule S23B346 -neighbors 7" or
      "xlock -mode life -pent2".
    New gliders found by David Bagley, one in 5 neighbors pentagonal life
      (-rule S24B2) "xlock -mode life -pent", the other in 9 neighbor
      triangular life "xlock -mode life -neighbors 9" (-rule S3B34).
      Associated periodic patterns for each added.
    Added more symmetries and now have all the random symmetries
      (at least I think so) for squares, hexagaons, triangles, and
      pentagons.
- Macro FTGL213 added for new FTGL library.  If you need it to compile
    text3d2.cc, make sure it compiles with -DFTGL213.  Should work
    automatically for VMS though, thanks to Jouk Jansen.
