There are now 3 code paths in decreasing speed:
First, optimize subsearching more by just hiding the actors
that didn't match, since we know the ordering has to be right.
For initiating a search (or backspacing an existing one), again
instead of destroying and recreating actors, just temporarily
remove them and re-add them in the desired order.
Finally for when data has changed, use the old code path of
destroying all actors. (This itself could obviously be optimized
if we had a way to know that just one application changed, but
at the moment we don't).

We queue a 150ms timeout when the user starts typing to avoid searching
for the first keystroke. However, this caused us to change to the search
mode, but show the leftover state of the search displays from an
earlier search state.
Instead, just hide the results sections until we've actually performed
the current search once.

This is probably not the biggest optimization that needs to be
made at least for application searching, but we can optimize the
case where we're going from a search of "fi" to "fire" by just
re-searching the list of things we already had that matched "fi"
instead of looping over everything.

This fixes a regression where we weren't using the correct event
timestamps, because for both of these we were sending an XClientMessage
to ourself.

First eliminate the variable WELL_ITEM_HSPACING since it was 0
and thus effectively was not used.
Add a new variable WELL_ITEM_MIN_HSPACING which is the minimum
space between grid items we allow. When computing layout, allow
for a number of columns less than 4 by using the minimum item
size.

Based on a patch from Colin Walters.
For various reasons I'd like a method which allows evaluation; say
log in from another machine and run "gnome-shell --repl" or something.
Also as a possible solution for the screensaver X grab issue, add
a (read/write) property "OverviewActive".

The menu is needed by the app switcher as well as the overview, so
make it slightly more generic and move the code to appIcon. Also add
support for drawing the menu either to the right of or below the icon.

Rather than having the mapping from window into "slots" (or
possible positions in the workspaces) be dependent on stacking
order, compute the minimum-motion which is a vector from one
top left corner to another. This order won't change as long
as the window set and their positions stay fixed.
There are two minimum motion algorithims; one simply computes
all possible placements by permuting the window list, up to
a current maximum of 5 windows. Past that (which also happens
to be the number where we switch to a grid), we use a "greedy"
algorithm which for each slot, finds the window with least motion
for that slot.
To break any ties, we use an internal integer in MetaWindow which
enumerates the order in which windows were created.

The "lightbox" effect had support for highlighting a particular
rectangular region on the taskbar when Alt-Tabbing to a minimized
window. Since we no longer use the taskbar, this code is just cruft
now.
Part of https://bugzilla.gnome.org/show_bug.cgi?id=590563
Refactor the current menu code to support both window selection
and "normal" menu items. Add a "New Window" item which does what
you'd expect.
Clean up the way we handle highlighting the window items to be
more direct; rather than looping over all items in most cases,
just directly manipulate one item

There are few uses for being able to exit the shell directly; my
current one is that the gtype debug infrastructure is implemented
as an atexit() handler.
This isn't a long-term solution; what we really want is for Alt-F2 to
just be an application search with a hack to detect shell commands,
but in the short term this allows us to run the magic 'lg' command
from the overview.

Rename beginModal/endModal to pushModal/popModal. All of the current callers
just want to ensure that we're in a modal state; they don't actually need to
fail if we already are.
These functions also now take the Clutter keyboard focus, while recording
the previous focus.

When we had a filtered set of windows, and want to exit the overview
into a particular window, what we do is re-show all the old windows
first, but don't reset the scaling on them. This will involve
some overlapping, but that's not a big deal because we'll immediately
get overlap anyways in the normal case zooming the windows back.

When the user click+hold+release over the icon, the effect we want
is for the menu to stick around.
Also, allow the user to mouse over the actual windows and select
them directly. If the user mouses over a window, reflect that in
the menu.
https://bugzilla.gnome.org/show_bug.cgi?id=594699
Callers will generally expect _popup and _popdown to be a no-op if
the menu is already in that state; make it so.
Also change the 'popdown' signal to be 'cancelled'; this is
clearer and allows us to avoid having activate also call popdown.

There are ton of different kinds of mouse even handlers in the overview;
WindowClone has several mouse-enter/leave handlers, we still have a variety
of classes not ported to ButtonBox and so incorrectly handling double-click,
etc.
Since we at present don't have anything in the overview area for which
it makes sense to interact with during the animation, create a transparent
event-eating box which we raise to the top during the animation.

controls if there is only one page of results
This makes the search results display more streamlined.
Make sure that we move the selection to a different section if we are going
from displaying a single section to displaying all and the section that
used to be displayed alone doesn't have any results.
When the user click+hold+release over the icon, the effect we want
is for the menu to stick around.
Also, allow the user to mouse over the actual windows and select
them directly. If the user mouses over a window, reflect that in
the menu.
We will be adding more search results sections, so we should store the intended
order of the search results sections and their properties in an array of data
structures.
This information allows us to have generic code for creating the search results
sections, moving the selection between them and transitioning between showing
all sections and a single section.
Rather than starting lightboxing only when the mouse enters the
menu, start it when an application filter is set.
Also delete a stale function in WindowClone from previous work.
