And set the dialog actor reactive. Specifically, we do not know whether
the parent actor is reactive or not, and we should not be changing that
from here, so do not use that actor to handle key events.

All callers have been updated to keep this handle to identify their
own grab.
Also, optionally use the windowing state to determine whether
the grab is suitable for the specific uses. This removes the need
to trying to grab twice in the places where we settle for a keyboard
grab.

With the presence of Clutter.grab(), this behaves differently enough
that needs some redoing. The larger difference is what actors are
eligible for handling events.
In the older code, a PopupMenuManager would ask the grabHelper to
capture events from all the stage, and selectively silence events
on any actor that is not the currently shown popup menu or the
"source" actor for any other popup in the group (i.e. those that
would pop up another menu).
But we don't want to just silence events, we want to emit the
correct set of crossing events when a popup menu is shown or closed,
this requires a backing ClutterGrab() on the currently shown menu.
Since the presence of a grab also affects the ability to have actors
outside the grab area to handle events, the PopupMenuManager now
must detect hovering and focus changes to other menu sources by
handling events on the grabbed popup itself.
Redo the grabbing over Main.pushModal/popModal (i.e. ClutterGrab,
plus keyboard focus restoration) and a captured event handler on
the currently shown menu, to make PopupMenuManager behave as it
is expected with this new kind of grabs.

This is subject to further possible simplifications. Use Clutter.grab
to redirect input and focus, a fundamental difference here is that
we do redirect input to the topmost owner of the grabhelper stack,
instead of the stage. This is better behaved with the presence of
other grabs, at the cost of some behavioral changes.

Despite this grab happening in the dialog, we are also interested in
things happening outside of it. Move this grab to happen in the stage
itself, so the changed grab semantics don't make it impossible to
interact with parts of the login screen.

While the menu is popped up, we artificially keep the icon highlighted
by ensuring it's hovered, and muting events on the app icon until the
menu is popped down.
This is somewhat convoluted and won't work with Clutter.grab(), where
it will be the menu itself that is the owner of input events while
shown, so cut some corners and explicitly tell the app icon to be
highlighted.

We want to mute things like pointers hovering the BoxPointer while
it does open. However keyboard events should still be handled
promptly.
Since Clutter.grab() will involve different actors being grabbed
and focused, this will have some more presence, e.g. when navigating
panel menus. We want to be able to navigate outside a menu while it
is still being shown.

Some dialogs like the runDialog expect this actor to receive
key events while it is not reactive. Whatever that black magic was
it will no longer work.
Make the actor reactive, so it can simply handle key events.

If a menu item in a submenu is part of a section, it should have
rounded bottom corners if both the item and the section are the
last child of its respective parent.
To express that, add a new .popup-menu-section class and use that
to undo/redo the rounding for items inside a section.
It would be possible to do without a new class with a selector like
> StBoxLayout > .popup-menu-item:last-child:hover,
:last-child > .popup-menu-item:last-child:hover
but that's hardly better with its heavy reliance on implementation
details.

The cursor texture, scale and position is captured separately and
overlaid on top of the preview, and on top of the final screenshot
image. This allows toggling it on and off post-factum.

Allow switching the screenshot mode by pressing the "s", "c", or "w" key. Also
implement arrow-key navigation between monitors in the screen screenshot mode
and between windows in the window screenshot mode.

UIWindowSelectorLayout is a stripped-down subclass of WorkspaceLayout
(we don't have to deal with windows disappearing or appearing or
changing size). UIWindowSelectorWindow is a heavily stripped-down
version of WindowPreview. UIWindowSelector is analogous to the Workspace
class.

As mentioned in the last commit, we'll split up taking screenshots into
creating a GPU texture first, and later saving that to disk as a PNG.
For individual windows it's already easy to get a ClutterContent with
the texture using meta_window_actor_paint_to_content (), for the stage
it's not that easy and involves a few extra steps including X11 specific
ones.
So introduce a new ShellScreenshot API which does all that and provides
the caller with a ClutterContent of the stage:
shell_screenshot_screenshot_stage_to_content ()

With the new screenshot UI we're introducing, we'll be capturing all
screenshots to textures on the GPU at first, and then create a PNG
stream from those textures at a later point. This will allow us to
present screenshots immediately to the user so they can inspect them and
select the right area before actually saving them to disk.
As a first step to make this work, introduce a new ShellScreenshot API
that writes an existing CoglTexture to a PNG output stream:
shell_screenshot_composite_to_stream ()
