In addition to the fixed-size mode that is used by the text view,
add a mode in which the magnifier requests enough size to render
the entire inspected widget at the current magnification. In this
mode, the magnifier will update its size when the size of the
inspected widget changes. Also, make the magnifier redraw on its
own whenever the inspected widget draws.
There is no good reason to assign the value directly.
Also, this fixes d23f3254b7
where widgets that chained up instead of calling
gtk_widget_set_allocation() would not draw becaues of empty clip.
(1) Get rid of supports_clip flag. All widgets (implicitly) support
clip.
(2) Don't reset the clip to { 0, 0, 0, 0 } before the "size-allocate"
signal.
(3) Make gtk_widget_set_allocation() set the clip (to the allocation).
This ensures that eveyr widget has a clip set.
Note: It overrides previous calls to gtk_widget_set_clip(), while in
3.14 this didn't happen.
(4) As the clip is set by gtk_widget_set_allocation() now, don't set
it after the "size-allocate" signal anymore.
This fixes calls to gtk_widget_queue_draw() from inside the
size_allocate vfunc.
We've observed hangs of mutter when it initializes GTK+, which
are caused by initializing GL, which in turn makes xwayland
call back into mutter. With this change, mutter should just
disable GL support in GDK, and things will work.
Override the gtk-shell-shows-app-menu and gtk-shell-shows-menubar
settings to FALSE, if we can detect that we are not on the same
session bus as the xsettings provider that we got these settings
from.
We determine this by comparing the bus ID of 'our' session
bus with the one reported in the Gtk/SessionBusId xsetting.
If they are different, then it very likely that we are in an ssh
situation where we see the forwarded X display, but not the
session bus. The D-Bus based menu exporting will not work
in this situation.

The magnifier is now set enough height to show the line being currently
manipulated, which makes it just big enough to show the layout height at
that size and magnification.
- It is not possible anymore to trigger text DnD through touch, pressing
and dragging from within the selection will instead extend it. Text
shrinking is still available through the handles
- The selection mode for touch is per-word, char-level manipulation is
still available through the handles.
- Tapping within the selection will bring in text handles, and toggle
text selection popover.
This mode could also shrink the selection, plus the starting point would
seem somewhat arbitrary (actually dependent on the dragging direction of
the last selection).
Made this mode more consistent by only allowing it to extend the selection,
only in one direction for each operation, and so it keeps the current
selection as a minimum.
Instead of passing a GdkEvent and let the function figure out whether the
selection should be extended, let that to the caller and just pass a
boolean here.
Using the parent widget context is a leftover of the pre-popover
implementation, which used GdkWindows directly. This will make the context
reflect widget state, at the expense of changing the selector paths
that used to match the handles.
Checking the return value was valid for most gestures, but
GtkGestureLongPress, where the first press triggers internally an action,
but does nothing for the sequence to be claimed/denied, FALSE was eventually
returned, and the button/sequence functions would be incorrect when
::pressed is emitted.
So check that the sequence is being handled by the gesture, this is more
desirable than the return value as it's independent of sequence state,
and still will be FALSE for the cases we want to catch here.
When a RTL paragraph is not set to wrap, the right margin is not respected
because of the margins counted twice so we replace
display->width by PIXEL_BOUND (extents.width), the same quantity
without the margins.

GtkIconTheme doesn't scale icons beyond the size specified in the theme
anymore. This can result in arbitrarily large menu items when a theme
only provides large icons.
Force icons to always be 16x16 to ensure that menu items always have the
same height.

Since the support for GL support in the GDK Windows backend has landed in
master, we need to build it in the Visual Studio builds. Update the
projects for that and "install" the public header that was added.
This adds support for OpenGL to the GDK Windows backend using the WGL API
calls, which enables programs that uses the GTK+ GLArea widgets to work on
Windows as well.
This also adds a simple utility function to query for the version of OpenGL
that is supported by the Windows system, like the one provided by the X11
backend.
Many thanks to Alex (and Emmanuele, who started the OpenGL integration in
GTK+) who offered advice and help along the way, as well as the X11 and
Wayland backend for this work to refer to and to model upon.

As the alignments, strides and image formats may be different across
platforms, make the texture upload a vfunc to allow backends to override
the GL commands for uploading textures for the software implementation for
gdk_gl_texture_from_surface(), if necessary.
Suggested by Alex to avoid copying non-trivial portions of code which would
then add maintainenace burden.

This drops the maybe_allocate_buffers that re-allocates buffers
at any point. Instead we just set have_buffers to FALSE and have
the buffers re-created when needed.
This also makes the buffer creation code imdeponent and makes it
clean up no longer needed buffers in order to handle being called
multiple times due to the above.
We also ensure we re-allocate the buffers when we're resizing
and the buffers are already created.
We can't combine multiple draws into one for the software fallback,
because each quad has a different texture. And we generally don't
want to make a larger single texture because then we would have
to upload more data.
