NoSymbol is not a valid GDK symbol (it only has the concept of
VoidSymbol, for some reason, which is neither the same thing nor
produced by any sane keymap). Passing NoSymbol events through to GTK+
apps is unlikely to produce anything useful.
In particular, this meant VTE would scroll to the end of the buffer when
pressing Fn (required for Page Up/Down on Macs), as it was receiving a
keypress that wasn't a modifeir. This does not happen on X11, as the
KEY_FN keycode is above 255, so does not get sent to clients.

We don't care about the specific (possibly client-side) window that
requested the focus here, only the toplevel. Fixes mistakenly sent
focus events when the grab happens inside the current focus window.

This avoids the g_source_remove(), g_source_destroy(),
g_timer_source_new(), and g_source_set_name_by_id() in the common case.
Instead, we reuse our previous source and update the ready time to our
new deadline. We lose the coalescing with g_timeout_add_seconds(), but
that is not going to help in the common case anyway (unless you have
three hands and can scroll multiple pixelcached backed widgets at once).

In non-composited environments, we were ending up with all-black
drag icons, because nothing was drawing the background of our new
toplevel. Fix this by drawing background when we are not composited.
We don't do this when composited, since we want to allow transparent
icons.
GtkPlacesView currently provides no example of
server addresses, which may confuse users.
To fix that, add a helper popover with some
guidance on server addresses.

The documentation clearly says that the widget is not destroyed,
but we were in fact failing to keep it alive, since it was still
a child or the icon_window when we destroy that. Fix this by
reparenting the icon_widget out before. Also, deal with the
possibility that the application might destroy the widget
halfway through, for whatever reason.
I added a new test function, but didn't actually use it.
No wonder I couldn't reproduce the lifecycle issues with
drag widgets that firefox is experiencing.
Always associate a drag context with a GdkDisplay and use that when
getting a cursor for a given action.
If we don't do this, dragging on a window that doesn't use the default
display will make us use cursors from the wrong display.

Typically, there won't be any references on old frame timings except for
the most recent timing. So instead of discarding these and re-entering
gslice twice, just steal the old frame timing and reuse it.

Don't track all orphaned dialogs globally, as mixing them up with each
other would in most cases trigger errors when we try to pass bogus
values to Wayland requests.

The naming of pointers to GdkWaylandDisplay's were inconsistent.
Running the following commands in gtk+/gdk/wayland illustrate the
inconsistency:
$ grep -r '\<display_wayland\>' *.[ch] | wc -l
195
$ grep -r '\<wayland_display\>' *.[ch] | wc -l
81
This patch renames all occurrences of "wayland_display" to
"display_wayland". This is also consistent with naming in the X11
backend. A couple of whitespace changes were done as well in places
where the rename was already done, that added line breaks to long lines
that stood out.

Generate .pc files for the package, so that it would be easier for
building introspection for packages that depend on GTK+. Also split
PythonPath into PythonPath and PythonPathX64 to facilitate the build of
introspection files, which need to have Python that is built with the
same ac=rchitecture where GTK+ is built.
Clean up the formatting and spacing a bit.
When synthesizing keyboard repeat, we can potentially drift further from
the mark depending on the timing of the frame callback and how long it
took to deliver the event.
This patch attempts to reduce this by tracking from a stable epoch the
time of our next keyboard repeat.

There are various functions to access links based on their index for
a11y. We can spare quite a few lines of code by just using
g_list_nth_data instead of iterating over the list ourselves.

We perform lots of gadget allocations that require allocating a
GtkBuiltinIcon. One notable example is the scrollbar for a scrolled
window.
In the process of doing this, we often calculate baseline information that
isn't necessary. With how much this code path gets exercised, its worth
catching the result for the common case, which is that the font-description
has not changed and we are using the default language the application
was started with.
This simply caches the previous result and verifies that we can reuse it
with pango_font_description_hash() and a simple language check.

This allows us to decide when the R and B color channels should be
flipped with a much better granularity.
For instance, when using GLX_EXT_texture_from_pixmap to create a GL
texture from a surface we don't need to swap the R and B channels, as
the internal representation of the texture data will already have the
appropriate colors.
We also don't need to flip color channels when blitting from a texture.
