If there is no secondary text, then the primary text is just a message,
not a title, and should not use title style.
This partially reverts 1e3ec7c1f9. The
message dialog nown looks like it used to in GTK 3. However, it's still
styled only using a style class rather than using pango markup, as in
GTK 3.
Fixes#3509
We were not aligning model button labels with nesting
submenus with indicators in their containing menu.
This was visible in the application demo of gtk4-demo.
According to OpenGL spec, a shader object will only be flagged
for deletion unless it has been detached; when a program object
is deleted, those shader objects attached to it will be detached
but not deleted unless they have already been flagged for deletion.
So we shall detach a shader object before it is deleted, and delete
it before the program object is deleted best.
Some GTK based applications such as Qemu UI create and manage
EGLSurfaces associated with the relevant GdkSurfaces. In order to create
an EGLSurface, there needs to be a way to pass the native window
object to eglCreateWindowSurface(). While running in an X environment,
the native window object can be obtained by calling
gdk_x11_surface_get_xid(). Likewise, the native window object can be
obtained by calling gdk_wayland_surface_get_wl_egl_window() while
running in a Wayland environment. Therefore, this API needs to be
exposed to apps.

The memory pointed to by GstVideoFrame::plane_data becomes invalid after
unmapping causing the GBytes to point at some random memory if the
unmapping is not deferred until its destroy notify.
When the GStreamer buffer is backed by normal system memory this is not
a problem but if it is backed by e.g. an OpenGL texture, dmabuf or some
other hardware-specific memory this will otherwise cause interesting
problems.
Here is a command to reproduce this testcase:
GDK_DEBUG=gl-gles gtk4-demo --run gears
Without this patch, Mesa throws this compile error:
0:130(13): error: no matching function for call to `mod(error, float)'; candidates are:
This is caused by `u_rotation - 90` being of type error since
`u_rotation` is a float and it’s illegal to subtract it with an integer.
Motion history coordinates are based on GdkSurface coordinates. Transform
the coordinates from the GtkNative they are received on, accounting for the
possible transforms (e.g. due to window borders and shadows).

If set to TRUE, does not call the free func for the removed items.
This can be used to move items between arrays without having to do the
refcounting dance.
1. That's a bad idea UI wise as you can't see the search after you
scrolled.
2. That's a bad idea code-wise because Listviews need to be put into
a ScrolledWindow or they won't scroll.
