We don't use them anymore, so drop them.

13c7020b80 background: fix pixbuf leak in load_file_finish
g_task_propagate_pointer relinishes the GTask
of its reference to the propagated pointer, so we need to
unref it ourselves when we're done with it.

5ed6e37e3c background: fix task leak in load_file_async
g_task_run_in_thread takes its own reference to the
task passed in, so we can unref the initial reference.

e216b6ca0f background: Fix the desaturate effect when on its own
We need to make sure cogl_texel is set to something,
otherwise we'll have junk.

6e831c88a6 compositor: fix background vignette for non-stretched styles
The background vignette currently fits itself to the painted
texture, instead of the monitor.  This causes some very
wrong looking drawing for backgrounds that don't fill the screen.

This commit reworks the vignette shader code to be clearer, more
correct, and parameterized so that it knows how to scale and
position the vignette.

0e3d164117 compositor: when tiling background, center on screen
The WALLPAPER style of background painting currently
draws starting in the upper left corner of each monitor.

This isn't really correct, it means the seam between
monitors doesn't match up and edges look unbalanced if
the tile isn't a multipe of monitor size.

Really, the tiles should be centered in the middle of
the screen.  (Just like when tiling a bathroom floor,
tiles should start in the center of the room.)

This commit reworks the math to make that happen.

e623406c99 background: Fix gradient color rendering
There is currently code to try to fill gradients in a
hardware native format, using #ifdefs. That optimization is
unimportant since gradients only use 2 byte buffers. It's
also incorrect because it's getting the channel order wrong
at buffer initialization time.

This commit drops the ifdefs for clarity and fixes the
channel order.

'code' may be used uninitialized in this function, so make sure
to return early in this case.

580feb0c85 compositor: rework how backgrounds are managed
Background handling in GNOME is very roundabout at the moment.

gnome-settings-daemon uses gnome-desktop to read the background from
disk into a screen-sized pixmap. It then sets the XID of that pixmap
on the _XROOTPMAP_ID root window property.

mutter puts that pixmap into a texture/actor which gnome-shell then
uses.

Having the gnome-settings-daemon detour from disk to screen means we
can't easily let the compositor handle transition effects when
switching backgrounds. Also, having the background actor be
per-screen instead of per-monitor means we may have oversized
textures in certain multihead setups.

This commit changes mutter to read backgrounds from disk itself, and
it changes backgrounds to be per-monitor.

This way background handling/compositing is left to the compositor.
