Since the blur sigma decides how many pixels get factored in when
blurring and setting a scale factor increases the background texture by
that factor, the sigma value should also be multiplied by the scale
factor.

If we modify the paint volume to make it larger and include the blur
radius, we should also use the gained size and draw something there.
Since the framebuffers are only the size of the actor to blur, we're not
doing that right now anyway, so remove the vfunc override.

Use the shader for linear sampling and incremental calculation of the
gaussian kernel values as it was implemented by Patrick Walton in
webrender.
The sigma value for the blur (the standard deviation) is calculated by
taking the blur radius and dividing it by 3, this value is used by most
implementations of gaussian blurs since it covers a high percentage of
the gaussian shape.
The linear sampling optimization is implemented by skipping every second
texel (i += 2) in the for-loop that's sampling adjacent texels.

Floor the downscaled size of the new framebuffer to make sure we don't
initialize a framebuffer with a floating point value that might be
interpreted wrong by `cogl_texture_2d_new_with_size` and end up with a
slightly wrong aspect ratio of the framebuffer.
This fixes situations where the widths or heights of downscaled
framebuffers sometimes miss some pixels at the border.
While at it, remove the `downscale_factor` argument from
`setup_projection_matrix` since that function doesn't need the initial
size of the actor anyway.

Now that we support extension updates, it may be useful to list
pending updates from the command line. It's easy enough to support,
so add a corresponding option to the list command.

There is nothing else to be focused in the lock screen itself -- the
top bar is already handled elsewhere, and the dialog manages itself
now.
Remove the lock screen group from the Ctrl-Alt-Tab manager.

AuthPrompt is the set of actors that contain the user avatar,
the username, and the password entry. With the removal of the
screen shield, the unlock dialog (be it UnlockDialog or the
LoginDialog) is always created, and in the case of UnlockDialog,
so is the auth prompt.
This is problematic, though, since for passwordless accounts,
the simple act of creating AuthPrompt authenticates the user,
and lifts the lock screen.
Create the AuthPrompt on demand in UnlockDialog.

As per the latest lock screen mockups, critical notifications must have
a more prominent, solid color.
Add a .critical style class to critical notification bubbles, and make
them darker.

Now that the screen shield is gone (at least, as it used to
be), the corresponding session mode is not necessary anymore
as well.
Remove the 'lock-screen' session mode, and the corresponding
CSS.

Pretty much what the commit title says.
This gives the lock shield actor another role: instead of
being the interactive screen shield, make it the invisible
actor that prevents interacting with windows while the
unlock dialog is sliding down.

Activating a dialog is slightly different from opening it; the
former is about showing the user authentication widgetry, while
the latter is about creating it and pre-allocating the necessary
resources.
Activate the screen shield dialog when necessary.

The 'onPrimary' argument was being passed to dialog.open(). Turns out,
neither UnlockDialog nor LoginDialog use this parameter.
Remove the unnecessary 'onPrimary' parameter, and cleanup the related
code.
