Instead of handling WM_DISPLAYCHANGE on every GdkWindow, only handle
it on an ad-hoc hidden window we create when opening the display.
This has two reasons:
1) we want emit the display::size-changed signal even if there are no
gtk windows currently open
2) we want to emit the signal just once and not once for every window

This is a variable holding a ref to an object, so it is
a great case to use g_set_object and g_clear_object.

We need to rename the projects so that when these projects are added
into an all-in-one solution file that will build the GTK+ 2/3 stack,
the names of the projects will not collide with the GTK+-2.x ones,
especially as GTK+-2.x and GTK+-3.x are done to co-exist on the same
system. This is due to the case that the MSVC projects are directly
carried over from the GTK+-2.x ones and was then updated for 3.x.
We still need to update the GUIDs of the projects, so that they won't
conflict with the GTK+-2.x ones.
Use the common automake module from the previous commit in the
Makefile.am's, which means that the Makefile.am's in gdk/ and gtk/ can be
cleaned up as a result. As a side effect, the property sheet that is used
to "install" the build results and headers can now be generated in terms of
the listing of headers to copy during 'make dist', where we can acquire
most of the list of headers to "install", so that we can largely avoid the
situation where the property sheet files are not updated in time for this,
causing missing headers when this build of GTK+ is being used.
Also use the Visual Studio Project file generation for the following
projects:
gtk3-demo
gtk3-demo-application
gtk3-icon-browser
gdk-win32
gdk-broadway
gail-util
So that the maintenace of these project files can be simplified as well.

Windows does not send any release key event for one of the shift keys
when both shift keys were pressed together. This commit solves
the problem by sending the extra release key event for the shift key
which was released as first, when the other shift key is released.
Other modifiers (e.g. Ctrl, Alt) do not have this problem.

Load themed cursors from the same places they are loaded on freedesktop systems,
but use W32 API functions to do so (works for .cur/.ani cursors instead of X
cursors).
Refactor the code for cursor handling. Prefer loading cursors by name.
Do not load actual cursors when loading the theme. Find the files and remember
the arguments/calls for loading them instead. Keeping HCURSOR instance in the
hashmap would result in multiple GdkCursors using the same HCURSOR. Given that
we use DestroyCursor() to off them, this would cause problems (at the very
least - DestroyCursor() would fail).
Store GdkCursor instances in a cache. Update cached cursors when theme changes.
Recognize "system" theme as a special (and default) case. When it is set,
prefer system cursors and fall back to Adwaita cursors and (as a last resort)
built-in X cursors. Otherwise prefer theme cursors and fall back to system and
X cursors.
Force GTK to use "left_ptr" cursor when no cursor is set. Using NULL makes
it use the system default "arrow", which is not the intended behaviour when
a non-system theme is selected.
Ignore cursor size setting and query the OS for the required cursor size, as
Windows (almost) does not allow setting cursors of arbitrary size.
https://bugzilla.gnome.org/show_bug.cgi?id=749287
In particular this means that cursors are disposed of by the way of
g_object_unref(), not DestroyCursor (which is documented to not to be
used on certain kinds of cursors, and we can't tell which is which).
It should also alleviate any concerns about destroying cursors that
are still in use by other windows, except for cases where we would
somehow get our hands on a HCURSOR that someone else is using and we
make a GdkCursor out of it and later unref and finalize it while it
is still in use.
It also removes the need to call CopyCursor(), which makes animated
cursors into non-animated ones as a side-effect (supposed to be a bug,
but try explaining that to MS). Now cursors should be animated (if
the are set up as such in the OS).

This is purely to support gdk_cursor_new_from_name().
In particular, its counterpart, gdk_cursor_new_for_display(), will not
be affected, because there's no GDK_LEFT_PTR_WATCH cursor type,
and because i don't have a fallback cursor bitmask for gdk/win32/xcursors.h
We now have proper checks for gdk_screen_is_composited() and a proper
implementation for gdk_screen_get_rgba_visual() for Windows, so we
can remove the comments in this file stating that they aren't
available for Windows.
Requires Vista and newer.
* Create surfaces with cairo_win32_surface_create_with_format
* Provide an rgba visual that can be distinguished from the system visual
* Make rgba visual the best available visual
* Enable alpha-transparency for all windows that we control
* Check for appropriate cairo capabilities at configure time
(W32 - 1.14.3 newer than 2015-04-14; others - 1.14.0)
* Check for composition support before enabling CSDs
* Re-enable transparency on WM_DWMCOMPOSITIONCHANGED
Windows that were created while composition was enabled and that were CSDed
as a result and will look ugly (thick black borders or no borders at all) once
composition is disabled.
If composition is enabled afterwards, they will return back to normal.
This happens, for example, when RDP session is opened to a desktop where a GTK
application is running. For W7/Vista windows will only re-gain transparency after
the RDP session is closed. For W8 transparency will only be gone momentarily.
Windows that were created while composition was disabled will not be CSDed
automatically and will use SSD (WM decorations), while windows that are CSDed
manually will get a thin square border.
If composition is enabled afterwards, these windows will not change.
This is most noticeable for system menus (popup menus are often generated
on the fly, system menus are created once) and some dialogues (About dialogue,
for example).

GdkKeymap already has support for _get_num_lock_state() and
_get_caps_lock_state(). Adding _get_scroll_lock_state() would be good
for completness and some backends (Windows?) could take advantage of
this.
This reverts commit 24d3f3fcb2.
Sorry, I am going to re-commit this very shortly with a new
commit message, as I found the commit message to be quite
wrong and misleading.
The current GdkScreen->is_composited() is a stub as we were having Windows
XP being supported, which does not support Desktop Window Manager (DWM),
which is used by Windows for composition.
Windows Vista and later support DWM, and it is always enabled on Windows 8/
Server 2012 and later.
Please note that as we are dropping XP support in this cycle, this is the
commit that would say goodbye to Windows XP support for GTK+-3.x, by
linking directly to dwmapi.dll. This means, we only check whether we are
on Windows 8 or Server 2012 (or later) to see whether we unconditionally
have composition enabled.

Use screen workarea to *also* set the position of a maximized window,
not just its size. Without this the window position defaults to 0:0
(the topleft corner), which is wrong when taskbar is position along the
top or left edge of the screen.

The existence of OpenGL implementations that do not provide the full
core profile compatibility because of reasons beyond the technical, like
llvmpipe not implementing floating point buffers, makes the existence of
GdkGLProfile and documenting the fact that we use core profiles a bit
harder.
Since we do not have any existing profile except the default, we can
remove the GdkGLProfile and its related API from GDK and GTK+, and sweep
the whole thing under the carpet, while we wait for an extension that
lets us ask for the most compatible profile possible.
https://bugzilla.gnome.org/show_bug.cgi?id=744407
Now that we have a two-stages GL context creation sequence, we can move
the profile to a pre-realize option, like the debug and forward
compatibility bits, or the GL version to use.
Emit an error if the profile is different.
This is a follow-up commit to commits cc45e82 (x11/gl: Ensure we use the
3.2 core profile) and 2d9081d (wayland/gl: Ensure we use the 3.2 core
profile), so that we do the same on GDK-Win32. Update variable names and
comments so that the code is clearer to people, as we still need a
temporary legacy WGL context first before we can use
wglCreateContextAttribsARB() to create a WGL core (3.2+) context.
https://bugzilla.gnome.org/show_bug.cgi?id=741946
Like what is being done in the X11 and Wayland backends, create the
GdkWin32GLContext in 2 steps, where we only create the actual WGL context
in _gdk_win32_gl_context_realize().
https://bugzilla.gnome.org/show_bug.cgi?id=741946
The default ->upload_texture() works also for Windows since commit 27cf0fa,
as some of the problems described in 742953 also applied for GL core
contexts on Windows as well before 27cf0fa. Clean up the GDK-Win32 code a
little bit as a result.
This function is given a barely setup GdkEvent, so the GdkDevice field
is still unset, causing warnings and misbehaviors when the position
is queried for it.
Given that the wintab GTK+ code seems to rely somewhat hard on the wintab
device managing the pointer cursor, query the pointer position from the
pointer itself.
https://bugzilla.gnome.org/show_bug.cgi?id=743330
The window used NULL as a parent window, which defaults internally to
using the root window of the default screen. But at the time wintab is
initialized, there is no default display/screen yet.
Fix this by retrieving this information from the given GdkDeviceManager,
so we don't have to wait for the display to be in place before
initialization.
