When we receive a DestroyNotify, we have to unmanage the client. However, we
were just informed that the window was destroyed, so it doesn't make sense to
try to do "something" with the window.
This commits fixes some errors from the X server (which we ignored, but still
they are gone now).

Lua now has access to a cairo surface via drawin.surface. When the drawing to

It is perfectly valid for a cairo surface to delay the actual. This is mostly
done in situations where it speeds stuff up. Since we want our drawing to be

If we called the widget layout for x widgets, but the layouts returned less
geometries than this, we silently ignored the left-over widgets. If the layouts
returned more geometries, we crashed.
Fix this by verifying that the number of widgets and the number of geometries
are equal. If they are different, we use the smaller of the two.

While drawing the wibox, the C core builds up a list of widgets and their
associated geometry. This list consists of widget_node_t objects and is
constructed like this (This is from luaA_table2widgets()):
widget_node_t w;
p_clear(&w, 1);
w.widget = luaA_object_ref_item(L, idx, -1);
widget_node_array_append(widgets, w);
After we are done with this list of widget nodes, it is freed via
wibox_widget_node_array_wipe(). However, wibox_widget_node_array_wipe() passed
"&w" to luaA_object_unref_item() while it should have used "w.widget" (which is
what was returned from luaA_object_ref_item()). This made the unref fail and the
wibox was carrying around a reference to this widget forever. This was
effectively a memory leak.

The systray bases its extents on the size of the wibox that it is contained in.
No idea how this is supposed to work when the systray doesn't get the full size,
but in a vertical wibox, using <height of wibox> * <number of icons in systray>
certainly doesn't work for computing the size.
The fix isn't hard: Check the wibox' orientation when drawing and base our
calculation on its width if its orientation is different from East.

Previously, if a client had nofocus == true, it wasn't unminimized if sth tried
to focus it. Also, if this client had the WM_TAKE_FOCUS protocol, the focusing
would fail since it's an error to set the input focus to an unviewable window.
For consistency, this also moves the code that sets a client's minimized
property to false into client_unban() since it doesn't make sense to have a
minimized client unbanned (i.e. visible).

This should fix an actual race condition:
- Client unmaps its window (UnmapNotify for awesome)
- Client maps its window (MapRequest for awesome)
- Due to the UnmapNotify: client_unmanage() runs and reparents the window back
to the root (ReparentNotify)
- Due to the MapRequest: client_manage() runs
- Due to the ReparentNotify: We call client_unmanage() again and now the
client's window is lost.

While a window is in the save set, it will automatically be made visible again
when awesome exits/dies. This makes sure that the next window manager will pick
this window up and handle it properly again.
But when a window explicitly asks not to be visible, it doesn't want to be
visible. Even if awesome dies. So we should remove the client's window from the
save set in client_unmanage.

When a wibox is destroyed or detached from a screen, it is wiped to clean up its
resources. This also includes destroying the window which is associated with the
wibox.
The problem here is that if the wibox contains the systray, the systray window
would automatically be destroyed since all childs of a window are destroyed when
said window is destroyed. To fix this, we kick out the systray window before
destroying the wibox' window.

When an application loses its connection to the X11 server, all the windows in
its save-set are saved by reparenting them back to their closest ancestor. Also,
to they are unconditionally mapped. This second property is exactly what we

starts up won't be managing them.

When one sets a client to fullscreen, this is what currently happens:
- lua code: c.fullscreen = true
- The C code emits request::fullscreen without having touched the client's
fullscreen property yet (c.fullscreen is still false)
- awful.ewmh changes the client's geometry to fullscreen via c:geometry()
- This causes property::geometry to be emitted
- awful.layout reacts on this and causes the screen to be re-arranged, undoing
the fullscreen geometry set in awful.ewmh
- The C code for c.fullscreen = true continues and actually changes the client's
fullscreen flag
The result of this is that we get a client which thinks it is fullscreen'd
without actually being that.
Fix this by first changing the client's fullscreen property and then emitting
request::fullscreen. Same thing for maximized_{vertical,horizontal}.

This makes imlib add images loaded from files to its image cache again. That way
we avoid loading the same image again and again (e.g. if you cycle through the
list layouts all the layout icons are loaded).
To not reintroduce FS#651 (fixed in 2dadce9b), we call
imlib_image_set_changes_on_disk(). This causes two stat() calls if the same file
is loaded again to check if the file's timestamps changed which is still less
expensive than loading the whole image again.

After the last patch, after each resize the X server fills the complete wibox
with its background color which means that the widgets will still flicker. This
patch fixes this by setting the wibox' bit gravity to NorthWest.
This means that if a wibox is enlarged, only the new, larger part will be filled
with the wibox' background color and the rest of the wibox' content will be left
intact. With this patch I couldn't see any flickering anymore.

Currently wiboxes have their background set to "inherit parent pixmap". That
means that each time a wibox is e.g. resized, the X server sets the wibox'
content to the wallpaper and then immediately awesome redraws the wibox with the
proper background. This causes flicker when you e.g. resize clients which have a
titlebar.
With this patch, wiboxes get their proper background color for their "back
pixel" value. Now, instead of showing the wallpaper, the X server will fill the
complete wibox with its background color.
With this patch, the actual widgets will still flicker. Also, if the wibox has a
background image, this image obviously won't be used by the X server and we get
some flicker again. My next patch will address these issues.
