In particular, allow specifying a filename for a GDK_TYPE_TEXTURE
property. This makes it easy to transition properties from Pixbuf type
to Texture type without having to touch resource files.
We cannot unrealize a renderer in the dispose function, because that
would cause this chain to happen:
gsk_gl_renderer_dispose
gsk_renderer_dispose
gsk_renderer_unrealize
gsk_gl_renderer_unrealize
So we would call into thje GL renderers unrealize when it has already
(partially) disposed itself and ause accesses to dead variables.
and gdk_texture_new_from_resource().
While doing set, turn all GDK_AVAILABLE_IN_3_90 into
GDK_AVAILABLE_IN_3_94 because that's now true after the renaming.
A sideeffect is that we don't set the correct parent window on child
widgets anymore, but that is hopefully going to be fixed once we get rid
of child windows completely.
Since on Windows we need to use a good amount of temporary GL contexts,
we need to switch back to the original GL contexts we were using when
we are done with the temporary GL contexts, otherwise multi-GL windows
will cause confusions causing display artifacts and crashes.
Also, use the GdkWin32GLContext::gl_hdc consistently throughout
the code and remove the GdkWin32Display::gl_hdc as Lukas K pointed out
that GdkWin32Display::gl_hdc becomes out-of-date and so the HDC that the
GL context is bound to becomes incorrect in sceanarios using multiple
windows with GtkGLArea/GdkGLArea items (which would cause the artifacts in
programs that use multiple windows with GtkGLArea/GdkGLArea items, and it
turns out that GdkWin32Display::gl_hdc is actually not necessary to help
keep track of the HDCs we use for our GL contexts.
This will also fix on Windows with GDK_GL=always, or when GSK's gl
renderer is used.

Move the leftovers from the removals to use the current APIs, to fix the
build. Also for gdk_device_virtual_set_window_cursor(), only do
something when a valid GdkCursor is passed in here.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Widgets can now set their favorite cursor using public API.
This is very necessary because all cursor-setting APIs are still
setting it on their GdkWindow, which by now is the toplevel - oops.
Change constructors to reflect that.
While doing so, also add a fallback argument to the cursor constructors,
so it is now possible to create cursors with fallback.
Instead of creating a GdkX11Cursor, create GdkCursors. Cache the XCursor
in a hash table instead.
Also, make use of the new fallback mechanism for fallback code: Make
sure to provide cursors for the names that are guaranteed to exist, but
do not do bad attempts at displaying texture surfaces.
Black/White/transparent is not a replacement for those.
The check used to achieve discarding events not meant for the window
widget itself (because they are handled in the regular paths). Using
the target widget is the equivalent now.
Use g_value_set/get_boxed() in gtk_window_get/set_property(), case PROP_ICON.
icon_from_list() shall always add a reference to the returned icon.
gtk_window_set_icon() must accept icon != NULL.

Stop wrapping the xsettings manager window in a foreign
window. This means that we cannot use the gdk window filter
APIs anymore, so just do the filtering in a non-generic
way.
