is destroyed, otherwise we can continue to receive events on the filter
when we no longer have a backing GdkWindow to act upon (causing a segfault.)

gathering thread during initialization.  Wait for the main window
to be realized before passing its cairo surface to the background
object and drawing the background for the first time.

We also need to make sure in our background's size_allocate function
to abort if we're not really active yet (no GdkWindow realized, and
no AnimateTimer yet).

Moved some background init stuff from the main window to the background
class for clarity, and removed the default_background setting - it is
already grabbing the default color in Background's class init.

correctly without it.  With it, entries are often under- or over-
allocated, with the result being the active user's password entry
sometimes does not have enough room to be visible.

entry box - it should be more centered now instead of in the upper left
corner.

slick-greeter should depend on lightdm

HiDPI shouldn't be activated on large screens where the dpi is OK.

Drawing the background on the root window causes the following issues:

- The settings daemon sets the DE resolution and that can break the aspect of the background
- Depending on configuration and distros, the background rendered by the greeter may or may not be the same as the users's.
- Some DEs such as Cinnamon render a login animation, which looks good on a black screen but not when a background is drawn.

Potential for regression:

Minimal DEs and WM should be tested to ensure the default state of the root window is OK.
We might have to clear that window or explicitly paint it black (or the background color chosen by the user).

Only support 1x and 2x scale ratios for now.

Also add a setting so the user can disable HiDPI support.

Slick-greeter sets the mouse cursor on the root window.
Without GKD_CORE_DEVICE_EVENTS set, the DE is unable to apply its own cursor theme and size.
