       * NEWS: 2.13.2 release

2005-11-18  Elijah Newren  <[email protected]>

       Merge of all the changes on the constraints_experiments branch.
       This is just a summary, to get the full ChangeLog of those
       changes (approx. 2000 lines):
         cvs -q -z3 update -Pd -r constraints_experiments
         cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog

       Bugs fixed:
         unfiled - constraints.c is overly complicated[1]
         unfiled - constraints.c is not robust when all constraints
                   cannot simultaneously be met (constraints need to be
                   prioritized)
         unfiled - keep-titlebar-onscreen constraint is decoration
                   unaware (since get_outermost_onscreen_positions()
                   forgets to include decorations)
         unfiled - keyboard snap-moving and snap-resizing snap to hidden
                   edges
          109553 - gravity w/ simultaneous move & resize doesn't work
          113601 - maximize vertical and horizontal should toggle and be
                   constrained
          122196 - windows show up under vertical panels
          122670 - jerky/random resizing of window via keyboard[2]
          124582 - keyboard and mouse snap-resizing and snap-moving
                   erroneously moves the window multidimensionally
          136307 - don't allow apps to resize themselves off the screen
                   (*cough* filechooser *cough*)
          142016, 143784 - windows should not span multiple xineramas
                   unless placed there by the user
          143145 - clamp new windows to screensize and force them
                   onscreen, if they'll fit
          144126 - Handle pathological strut lists sanely[3]
          149867 - fixed aspect ratio windows are difficult to resize[4]
          152898 - make screen edges consistent; allow easy slamming of
                   windows into the left, right, and bottom edges of the
                   screen too.
          154706 - bouncing weirdness at screen edge with keyboard moving
                   or resizing
          156699 - avoid struts when placing windows, if possible (nasty
                   a11y blocker)
          302456 - dragging offscreen too restrictive
          304857 - wireframe moving off the top of the screen is misleading
          308521 - make uni-directional resizing easier with
                   alt-middle-drag and prevent the occasional super
                   annoying resize-the-wrong-side(s) behavior
          312007 - snap-resize moves windows with a minimum size
                   constraint
          312104 - resizing the top of a window can cause the bottom to
                   grow
          319351 - don't instantly snap on mouse-move-snapping, remove
                   braindeadedness of having order of releasing shift and
                   releasing button press matter so much

          [1] fixed in my opinion, anyway.
          [2] Actually, it's not totally fixed--it's just annoying
              instead of almost completely unusable.  Matthias had a
              suggestion that may fix the remainder of the problems (see
              http://tinyurl.com/bwzuu).
          [3] This bug was originally about not-quite-so-pathological
              cases but was left open for the worse cases. The code from
              the branch handles the remainder of the cases mentioned in
              this bug.
          [4] Actually, although it's far better there's still some minor
              issues left: a slight drift that's only noticeable after
              lots of resizing, and potential problems with partially
              onscreen constraints due to not clearing any
              fixed_directions flags (aspect ratio windows get resized in
              both directions and thus aren't fixed in one of them)

       New feature:
           81704 - edge resistance for user move and resize operations;
                   in particular 3 different kinds of resistance are
                   implemented:
                Pixel-Distance: window movement is resisted when it
                  aligns with an edge unless the movement is greater than
                  a threshold number of pixels
                Timeout: window movement past an edge is prevented until
                  a certain amount of time has elapsed during the
                  operation since the first request to move it past that
                  edge
                Keyboard-Buildup: when moving or resizing with the
                  keyboard, once a window is aligned with a certain edge
                  it cannot move past until the correct direction has
                  been pressed enough times (e.g. 2 or 3 times)

       Major changes:
         - constraints.c has been rewritten; very few lines of code from
           the old version remain.  There is a comment near the top of
           the function explaining the basics of how the new framework
           works.  A more detailed explanation can be found in
           doc/how-constraints-works.txt
         - edge-resistance.[ch] are new files implementing edge-resistance.
         - boxes.[ch] are new files containing low-level error-prone
           functions used heavily in constraints.c and edge-resistance.c,
           among various places throughout the code.  testboxes.c
           contains a thorough testsuite for the boxes.[ch] functions
           compiled into a program, testboxes.
         - meta_window_move_resize_internal() *must* be told the gravity
           of the associated operation (if it's just a move operation,
           the gravity will be ignored, but for resize and move+resize
           the correct value is needed)
         - the craziness of different values that
           meta_window_move_resize_internal() accepts has been documented
           in a large comment at the beginning of the function.  It may
           be possible to clean this up some, but until then things will
           remain as they were before--caller beware.
         - screen and xinerama usable areas (i.e. places not covered by
           e.g. panels) are cached in the workspace now, as are the
           screen and xinerama edges.  These get updated with the
           workarea in src/workspace.c:ensure_work_areas_validated()
