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
Users of the GdkGLContext API should be allowed to set properties on the
shim GdkGLContext instance prior to realization, so that the
backend-specific implementation can use the value of those properties
when creating the windowing system specific resources.
The main three options are:
• a major/minor version tuple, to request a specific GL version
• a debug bit, to request a "debug context", which provides additional
validation and run time checking
• a forward compatibility bit, to request a context that does not
have deprecated functionality

One of the major requests by OpenGL users has been the ability to
specify settings when creating a GL context, like the version to use
or whether the debug support should be enabled.
We have a couple of requirements in terms of API:
• avoid, if at all possible, the "C arrays of integers with
attribute, value pairs", which are hard to write and hard
to bind in non-C languages.
• allow failing in a recoverable way.
• do not make the GL context creation API a mess of arguments.
Looking at prior art, it seems that a common pattern is to split the
construction phase in two:
• a first phase that creates a GL context wrapper object and
does preliminary checks on the environment.
• a second phase that creates the backend-specific GL object.
We adopted a similar pattern:
• gdk_window_create_gl_context() creates a GdkGLContext
• gdk_gl_context_realize() creates the underlying resources
Calling gdk_gl_context_make_current() also realizes the context, so
simple GL users do not need to care. Advanced users will want to
call gdk_window_create_gl_context(), set up the optional requirements,
and then call gdk_gl_context_realize(). If either of these two steps
fails, it's possible to recover by changing the requirements, or simply
creating a new GdkGLContext instance.

This avoids showing the scrollbars if we are positive the child widget
is being manipulated, regardless of the pointer being close to any of these.
On the next motion event after finishing the operation, the scrollbar will
be shown if necessary.

is_visible() wasn't the right check to perform here before unmapping,
and gtk_widget_unmap() already avoids being doubly called by checking
gtk_widget_get_mapped() anyway.
Rename the "install" projects as "gtk-install" as we are planning to have a
grand solution file that incorporates all project files of the GTK+ stack
with their dependencies, to make it easier for people to build GTK+ from
scratch from a stock installation of Visual Studio 2008 and later.
In that case the scrolledwindow still gets events through the captured
handler, and can thus still control visibility, so hiding the indicators
in this case can only lead to flashing.
This will be used to just detect when an edge of the scrollable area is
reached - as opposed to the edge-overshot signal that is emitted when
the user scrolls past the edge.

If a side of the box is 0px wide, make the corners owned by the adjacent
sides. This avoids spilling over of unwanted colors from the 0-width
side into the corner.
This is the fix that should actually have been part of
7e5ac3a58d but my amazing amending skills
got rid of it when amending the test.
Commit ff256956b2 introduced a frame_clock_events_paused
flag, but only ever set it to TRUE, instead of unsetting it when
events are resumed. This was leading to assertion failures in
_gdk_display_unpause_events().
Arrange things so that gtk-xdg-hinting==-1 and gtk-xfg-antialias==-1
end up as CAIRO_HINT_STYLE_DEFAULT and CAIRO_ANTIALIAS_DEFAULT in the
cairo font options.
This will not change anything on Linux desktops where xsettings will
always provide values different from -1. But on other platforms, we
can benefit from getting the platform-specific defaults in cairo.
Based on the first patch in:
https://bugzilla.gnome.org/show_bug.cgi?id=735316
If we are disconnecting from a frame clock that has paused event
processing and hasn't issued a resume yet make sure we resume the
events or they will stay blocked forever.

The code here was always a bit buggy: We removed the tab from
the notebook in a ::drag-data-received handler. But with
GTK_DEST_DEFAULT_DROP, that signal is emitted before we inform
the source side that the drag is finished. With its improved drag
handling, GtkNotebook now interprets this as a 'spontaneous'
removal of the tab being dragged, and cancels the drag, leading
to an unwanted cancel animation.
The easiest fix is to just defer the tab removal to an idle.
When a tab is dropped, we have to remove it from the notebook to
insert it elsewhere. This is expected part of the tab dnd operation,
and we need to differentiate it from 'spontaneous' removals which
cause us to cancel the drag operation.
