When an actor carrying canvas content is repainted, it will currently reupload
the data from the buffer to a texture. While this is not a performance problem
on a desktop, some mobile environments take a big performance hit. This
change tracks data changes and only recreates the texture if necessary.

By creating and starting the timer on clutter_main() an assumption is made
that that is how the main loop will be run for all clutter applications.
With more and more applications moving to GApplication, this assumption no
longer holds true.
Moving to clutter_init() means we are starting the timer earlier than we
should, and by not stopping it when the main loop quits we are taking a
measure that is later than we should. I believe it is safe to consider
those are close enough to the actual beginning and quitting of the main
loop in practice.

Instead of just bailing out when initializing the test suite, we can do
a much better job and skip all the tests. This means that the TAP driver
will work correctly instead of dying a horrible death, and we get a nice
report with a proper cause of the test skipping.
Without a paint() implementation in clutter-stage, the function
from clutter-group is used. That class has its own child list,
but attempts to use sort_depth_order, which is empty in this case.
This provides a partial fix by replacing a minimal paint(), see:

Commit e70a0109 simplified the dispatching of events by passing the event's
owernership to ClutterStage, but it may be so that any.stage is NULL at
some point on Windows, which will either cause _clutter_stage_queue_event()
to crash or issue a critical warning. Avoid this problem by checking
whether event->any.stage is not NULL before trying to call
_clutter_stage_queue_event().

...so that its entries will reflect the entries that are checked by the
autotools builds on config.h.in. Also take into consideration for MinGW
builds and for newer Visual Studio versions, such as the availability for
inttypes.h. Update the layout of the file cosmetic-wise as well.
Clutter, like GTK+ and GLib, has recently switched to a visibility-based
method of exporting symbols, so update the Visual Studio build files to
do likewise, by using __declspec (dllexport). This eliminats the need to
use a .def file to export the symbols. The pre-configured
config.h.win32.in is also updated accordingly for this purpose. The
clutter.symbols file can be dropped if it is not being used otherwise.
Instead of listing every public symbol inside an ancillary file, we can
use compiler annotations. This scheme is also used by GLib and GTK+.
The symbols file is left in tree until the Visual Studio rules are
fixed, but it's not used any more during distcheck.
I double-checked that the exposed ABI is the same before and after this
change, except for symbols that were never meant to be public in the
first place, and that escaped our attention when we generated the first
version of the symbols file.
All backends follow the same pattern of queueing events first in
ClutterMainContext, then copying them to a ClutterStage queue and
immediately free them. Instead, we can just pass ownership of events
directly to ClutterStage thus avoiding the allocation and copy in
between.

Keep track of the button modifier mask state in
ClutterInputDeviceWayland and push its state to new button events going
out.

We do not strictly require the 'swap-region' Cogl feature in order to use
clipped redraws: they work equally well with just the 'buffer-age' Cogl
feature.
https://bugzilla.gnome.org/show_bug.cgi?id=726313
_clutter_stage_window_can_clip_redraws is used to check for clipped redraws
support but can_clip_redraws is not implemented by clutter-stage-wayland so
it always returns FALSE causing full screen redraws.
Fix that by implementing can_clip_redraws in clutter-stage-wayland.

There could be times when we may not necessarily see a device appear
at initialization time, like when we're VT switched away when we
initialize, and thus we can't ever rely on a main seat appearing.
Always create a main seat with logical pointer/keyboard devices, and
tie the first physical seat that comes in to the main seat.
https://bugzilla.gnome.org/show_bug.cgi?id=726199
We're going to create the main seat at an earlier time, when
we don't have the physical libinput_seat yet, so we need to
do the association later.

The GetSystemMetrics() function returns wrong values for SM_CXSIZEFRAME,
SM_CYSIZEFRAME, SM_CXFIXEDFRAME and SM_CYFIXEDFRAME when built with Visual
Studio 2012 and 2013 (unless the XP compatibility setting for the
PlatformToolset entry is turned on), causing the window of Clutter programs
to automatically shrink to a point where they become unusable.
This patch uses AdjustWindowRectEx() for builds using Visual Studio 2012
and later, which deduces the required height and width of the Window
properly. Unfortunately we can't use this for the VS 2008/2010 builds as
they cause the Window to continually expand as the program is run.
