      Add MapQuest-style pan and zoom controls to the floormap.php3 page, and · aa7d57a9

      generally improve the clarity and appearance of the maps.  The scale factor
      buttons numbered 1-5 actually correspond to scale factors of 1, 1.5, 2, 2.5,
      and 3.
      
      Notice that the floorimages table in the database now has an integer "scale"
      column to distinguish the cached zoomed-in images with a suffix "-[1-5].jpg" .
      
      I use jpeg files instead of the png files that were used before.  They look as
      good or better, and are a third the size.  Panning around at a given zoom
      factor just involves cropping out a different rectangle of the scaled-up
      images.
      
      The 0311X064_[1-4]fl.pdf floor map files we got from Michael Kay started
      out life in Adobe Illustrator.  Although GhostScript/gv crash while
      trying to draw the pdf files, extracting them into PostScript files in
      Acrobat on Coke allows GhostScript to render them flawlessly.
      
      I started out using gs to render jpeg files in the shell, and then
      found that ImageMagick uses the same GhostScript renderer, and nicely
      handles cropping, drawing and annotations, and format conversion as well.
      
      The PostScript rendering gets slow at higher zoom factors.  So I cache the
      zoomed floor images, scaled up by rendering the PostScript files at a finer
      dot-pitch (density) in GhostScript, and then cropping out the right rectangle
      to register them properly.
      
      For readability, and to avoid having the thin lines and bitmap fonts used in
      some parts of the PostScript map from falling between the pixel cracks, I
      actually render at twice the pixel density and filter down to the final image
      with a gaussian -sharpen option to keep it from looking blurry.
      
      ImageMagick is callable from both the shell and as the Image::Magick package
      in Perl.  I converted the Perl logic in floormap.in to use Image::Magick
      instead of the GD graphics library, resulting in anti-aliased (smoothed)
      drawing of the wireless node dots and labels on floor maps for a better
      appearance.  Then I added optional scaling and centering arguments which
      select the proper cached zoomed-in image, and drive the logic for cropping and
      drawing.
      
      I modified the floormap.php3 file to wrap an input form around a set of zoom
      control buttons and the floormap image.  The zoom buttons set the scale
      argument to the Perl floormap script called on the server.  The floor map
      image itself is wrapped in a graphical submit button, so clicking on it
      returns the mouse coordinates within the image, which are then sent to the
      centering argument of the Perl script.

      ops as the user, but that breaks for admin people who have real shells
      on boss and no unencrypted key in the .ssh dir. So, switched it to a
      root ssh, and a simple proxy on the other side that flips to the user
      and invokes the run_linktest stuff.

      Small change to suexec code. This change has the potential for creating · 7e731fba
      Leigh B. Stoller authored
      unanticipated breakage. If that happens, just need to back out the
      changes under the "suexec-stuff" tag. However, the better solution will
      probably be to fix the PHP scripts that break by adding the proper
      groups in the call to suexec (in the web page, see below) or by fixing
      the backend Perl script that breaks.
      
      This fix is primarily to address the problem of some users being in more
      groups (cause of subgroups) then the max number of groups allowed
      (NGROUPS).  The groups that really mattered (say, for creating an
      experiment in a subgroup) could be left out cause they were at the end
      of the list.
      
      * suexec.c: Change how groups are handled. Instead of taking a single
        gid argument (the gid to setgid as), now takes a comma separated list
        of groups. Further, instead of doing a setgroups to the user's entire
        group list as specified in the groups file (getgroups), setgroups to
        just the groups listed on the command line, plus the user's primary
        group from the password file (this is to prevent potential breakage
        with accessing files from the users homedir, although might not really
        be necessary).
      
        This change is somewhat rational in the sense that in our case, suexec
        is not being used to run arbitrary user code (CGIs), but only to run
        specific scripts that we say should be run. The environment for
        running those scripts can be more tightly controlled then it would
        otherwise need to be if running some random CGI the user has in his
        public html directory.
      
      * www: Change the gid argument to SUEXEC() in a number of scripts so
        that the project and subgroup are explicitly given to suexec, as
        described above. For example, in beginexp:
      
      	SUEXEC(gid, "$pid,$unix_gid", ....);
      
        Aside: note that project names (pid) are always one to one with their
        unix group name, but subgroup names are not, and *always* have to be
        looked up in the DB, hence the "unix_gid" argument.
      
        Script breakage should require nothing more then adding the proper
        group to the list as above.
