Use GdkFrameClock for the timing of GtkTimeline. This require the
user to provide either a GtkWidget or a GdkFrameClock when creating
the timeline. The default constructor now takes a GtkWidget. If you
want to create a GdkFrameClock without a widget, you need to use
g_object_new() and pass in a GdkFrameClock and GdkScreen.

The frames-per-second for an animation should be controlled by how
fast we can process frames and the the frame-rate of the display; it's not
a meaningful app-settable property.

Add back the GtkTimeline code that previously made private and
then removed. It will be hooked up to GdkFrameClock. This commit
purely adds the old code back.

Switch GtkStyleContext to using GdkFrameClock. To do this, add a new
UPDATE phase to GdkFrameClock.
Add a GdkFrameClockTarget interface with a single set_clock() method,
and use this to deal with the fact that GtkWidget only has a frame
clock when realized.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
If the backend is throttling paints, then the frame clock will be
frozen at the end of the frame. If not, then we need to add throttling,
so wait until 16ms after the start of the frame before beginning the
next frame.

By starting with an odd frame counter value, we make the mapping
and initial paint of the window an atomic operation, avoiding
any visual artifacts from an unpainted window.
Possible improvement: start the frame when doing gdk_window_show(),
so that the same improvement occurs for windows that were previously
shown and are being mapped again.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
When a window is unmapped, freeze its frame clock. This avoids doing
unnecessary work, but also means that we won't block waiting for
_NET_WM_FRAME_DRAWN messages that will never be received since the
frame ended while the window was withdrawn.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
As part of the extended _NET_WM_SYNC_REQUEST_COUNTER protocol,
we get a _NET_WM_FRAME_DRAWN message for each frame we draw. Use this
to synchronize the updates we are doing with the compositing manager's
drawing, and ultimately with with display refresh.
We now set the sync request counters on all windows, including
override-redirect windows, since it is also useful to do synchronized,
atomic updates for such windows.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
By exporting two XSync counters on a toplevel window, we subscribe
to an extended form of the _NET_WM_SYNC_REQUEST_COUNTER protocol,
where the window manager can initiate an atomic frame, as previously,
but the application can also do so by incrementing the new counter to
an odd value, and then to an even value to finish the frame.

The support for 64-bit integers that GLib requires is used to
simplify the logic.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Add the ability to freeze a frame clock, which pauses its operation,
then thaw it again later to resume.
Initially this is used to implement freezing updates when we are
waiting for ConfigureNotify in response to changing the size of
a toplevel.
We need a per-window clock for this to work properly, so add that
for the X11 backend.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Instead of having gdk_frame_clock_request_frame() have
gdk_frame_clock_request_phase() where we can say what phase we need.
This allows us to know if we get a frame-request during layout whether
it's just a request for drawing from the layout, or whether another
layout phase is needed.

We may receive events because SubstructureNotifyMask has been selected
for the root window. (Most likely, this would occur because GTK+
is being used inside a window manager like Metacity or Mutter.)
This can confuse various types of internal accounting, so detect
such events and comprehensively ignore them for GDK's internal
purposes. We still need to generate GDK events for these cases
because you can select for substructure events with
GDK_SUBSTRUCTURE_MASK.

This is necessary in order to have async operations on it.
All the old copy/free functions keeps working, and g_boxed_copy on a GObject
also works, so this should be mostly compatible, but techncally its a minor
ABI break since the GType changes fundamental type. Changes like this has
happened before though, like with GVariant becomming its own fundamental
type.

These are generic tests that can test the button in all of its modes,
instead of hand-written tests for each combination.
Some tests fail currently.

If the user didn't explicitly select anything, BUT the file chooser button has
a current_folder set, do the same as what GtkFileChooserDefault would do:
return the current folder as the selection.
This makes the tests in tests/filechooser pass!

If no file was originally selected in the GtkFileChooserButton, then its
internal dialog is brought up and cancelled, then we need to restore the
selection back to none. GtkFileChooser, though, doesn't like to
select a NULL file, so call _unselect_all() in that condition.

The button's underlying file chooser dialog should not be used to store the file selection
while the dialog is unmapped. Instead, the file chooser button now stores the
selection itself.
Signed-off-by: Federico Mena Quintero <federico@gnome.org>
It used to fetch a possibly multiple selection from the GtkFileChooserDialog, and then
pick just the first item from the selection list. But since GtkFileChooserButton
operates in single-selection mode only, it can simply use gtk_file_chooser_get_file()
instead.
Also, the right way to reset the selection for GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER
is with gtk_file_chooser_select_file(), not with _set_current_folder_file().

This code came from a home-grown testing mechanism, which didn't aggregate tests
into a test suite; it just ran them one by one. Here we move some of that machinery
to GTestDataFunc for more flexibility in running tests.

This adds a way to get the gtk_widget_set_opacity liike behaviour
of retargeting GdkWindows and exposing every child in ::draw, without
actually having an alpha. This is needed if you're doing more complex things
such as cross fading of widgets.
We do this as a hack by using opacity values that round to 255 yet not
really 1.0 in order to avoid having some magical API call for this
mainly internal call.
