Subtle bugs remained on both Cygwin and Linux that caused the various
window panes to be restored in positions different than where the user
last placed them. Sergey Vlasov posed a pair of suggested fixes to this,
what is done here is slightly different. The basic fix here involves
a) explicitly remembering and restoring the sash positions for the upper
window, and b) using paneconfigure to redundantly set height and width of
other elements. This redundancy is needed as Cygwin Tcl has a nasty habit
of setting pane sizes to zero if their slaves are not configured with a
specific size, but Linux Tcl does not honor the specific size given.

gitk was saving widget sizes and positions when the main window was
destroyed, which is after all child widgets are destroyed. The cure
is to trap the WM_DELETE_WINDOW event before the gui is torn down. Also,
the saved geometry was captured using "winfo geometry .", rather than
"wm geometry ." Under Linux, these two return different answers and the
latter one is correct.

[jc: credit goes to Brett Schwarz for suggesting the use of "wm protocol";
 I also squashed the follow-up patch to remove extraneous -0
 from expressions.]

The gitk gui layout was completely broken on Cygwin. If gitk was started
without previous geometry in ~/.gitk, the user could drag the window sashes
to get a useable layout. However, if ~/.gitk existed, this was not possible
at all.

The fix was to rewrite makewindow, changing the toplevel containers and
the particular geometry information saved between sessions. Numerous bugs
in both the Cygwin and the Linux Tk versions make this a delicate
balancing act: the version here works in both but many subtle variants
are competely broken in one or the other environment.

Three user visible changes result:
1 - The viewer is fully functional under Cygwin.
2 - The search bar moves from the bottom to the top of the lower left
    pane. This was necessary to get around a layout problem on Cygwin.
3 - The window size and position is saved and restored between sessions.
    Again, this is necessary to get around a layout problem on Cygwin.

It seems that under Mac OS X, the menus get some extra entries (or
possibly fewer entries), leading to references to entries by an
absolute number being off.  This leads to an error when invoking
gitk --all under Mac OS X, because the "Edit view" and "Delete view"
entries aren't were gitk expects them, and so enabling them gives an
error.

This changes the code so it refers to menu entries by their content,
which should solve the problem.

When inserting the new commit row for the cherry-picked commit, we weren't
advancing the selected line (if there is one), and we weren't updating
commitlisted properly.

This restructures layoutmore so that it can take a time limit and do
limited amounts of graph layout and graph optimization, and return 1
if it exceeded the time limit before finishing everything it could do.
Also getcommitlines reads at most half a megabyte each time, to limit
the time it spends parsing the commits to about a tenth of a second.

Also got rid of the unused ncmupdate variable while I was at it.

This does a git-cherry-pick -r to cherry-pick the commit that was
right-clicked on to the head of the current branch.  This would work
better with some minor changes to the git-cherry-pick script.

Along the way, this changes desc_heads to record the names of the
descendent heads rather than their IDs.

This is a small extension to the code that reads the complete commit
graph, to make it compute descendent heads as well as descendent tags.
We don't exclude descendent heads that are descendents of other
descendent heads as we do for tags, since it is useful to know all the
branches that a commit is on.
Signed-off-by: NPaul Mackerras <paulus@samba.org>

This adds a feature to the diff display window where it will show
the tags that this commit follows (is a descendent of) and precedes
(is an ancestor of).  Specifically, it will show the tags for all
tagged descendents that are not a descendent of another tagged
descendent of this commit, and the tags for all tagged ancestors
that are not ancestors of another tagged ancestor of this commit.

To do this, gitk reads the complete commit graph using git rev-list
and performs a couple of traversals of the tree.  This is done in
the background, but since it can be time-consuming, there is an option
to turn it off in the `edit preferences' window.
