This patch optimizes window resizes by assuming that if a widget
has the same height at a width of 50 as with a width of 150, the
height for width 100 will also be the same.
The patch also further optimizes the cache allocator, now there
are 2 pointer arrays of up to a maximum of 5 requests, the arrays
will only be allocated if a request is ever made in that orientation
and the array will be sparse until each request is made (i.e. if a
label can only wrap to 3 lines, there will only be 3 out of a
possible 5 SizeRequest structures allocated to cache it).
This patch makes contextual height-for-width request caching
optional (the contextual cache is not allocated for widgets that
report GTK_SIZE_REQUEST_CONSTANT_SIZE).
The constant size request mode defines a request mode where
height-for-width geometry is unneeded, thus optimizing GTK+
by reducing the overall amount of requests that need to be
performed and cached while resizing an interface.
gtk_settings_get_default() was used to monitor the
"gtk-application-prefers-dark-theme" setting, rather
than the GtkSettings object associated with the window's
screen.
Fixes Bug 639584 - initial emission of GtkWidget:style-set is
not happening.
GtkWidget was filtering out ::style-updated (and ::style-set)
emissions until the widget was realized in order to avoid often
useless updates during widget construction and placing.
This is now done instead until the widget has a parent/screen,
which ensures the initial emission happen prior to the first
size negociation, while still filtering out all early emissions
during construction.
You can select something, but moving the focus somewhere else, or bringing up
the context menu makes the selection go away. This makes it impossible to
copy-paste the text.
The reason for this regression is that gtk_label_state_changed was sloppy and
assumed that it would only ever be called when a labels goes insensitive, which
is no longer the case.
The patch fixes things by explicitly checking if the widget is insensitive, and
only resetting the selection in that case, which is the same behaviour we have
for e.g. GtkEntry.
It turns out the bug is more complicated than I originally understood.
Not replacing the font description fields while merging here makes it
impossible for application's CSS to override fonts.

Use the background color instead.
I think the optimal solution would be delegating the shadow rendering to
the theme completely, and removing this in GtkThemingEngine, but for
now, this simple fix makes the dark variant more usable.

The metacity theme format allows to use colors from the current
GTK+ theme in window decorations. Since GTK+ now gained support
for dark theme variants, window managers using that theme format
(metacity, mutter, compiz via gtk-window-decorator) should be able
to use colors from the correct variant; so in case a variant is
requested, export it in the _GTK_THEME_VARIANT property on
toplevel windows.

gtk_entry_set_placeholder_text() makes the entry display the given text
when it is empty and unfocused. Based on previous patch by Alberto
Garcia.

We were ignoring the focus ring padding, and we were incorrectly setting
handle_x to padding.left, while the draw handler already takes padding
into account while redrawing.

XSendEvent doesn't currently work with XI2 events, so add code to
translate core events when they have the send_event flag.
(We still don't actually select for core pointer/keyboard events, so
we will only receive send_event events that are sent with a 0
event_mask.)

When tabs are not shown, and the notebook is used as a container,
we should not set the notebook style, otherwise the theme has no
way to know whether tabs are shown or not, and which colour to draw
the background.

Writing onto the passed-in GtkStateData could cause changes that would
propagate to siblings, as the data was not reset again.
By copying the data structure, this is avoided and the proper values are
passed to sibling widgets.
