No need to subclass this.

We want to subclass this in print backends,
but we don't want to allow out-of-tree subclassing.

Name this header gtkprinterprivate.h, following
our convention for private headers.

This should not be subclassed.

Nobody should subclass this.

No subclassing needed.

This should not be subclassed.

Nobody should subclass GtkIconTheme or GtkIconInfo.

Given that GtkSourceView exists, we will have
to keep GtkTextView subclassable until a replacement
appears.

No need to derive from it.

The docs for gdk_surface_invalidate_region were
talking about a no-longer-existing argument.

This triggers critials, and does us no good.

We also print the script, but we don't parse it yet.

... when a window gets hidden and later reshown.

The code now properly cleans up a window when it gets unmapped instead
of trying to retain previous updates information.

wayland: Use scale from core wl_output protocol

Closes #1901

See merge request !870

The “xdg-output” protocol provides clients with the outputs size and
position in compositor coordinates, and does not provide the output
scale which is already provided by the core “wl_output” protocol.

So when receiving the wl_output scale event, we should update the scale
regardless of “xdg-output” support, otherwise the scale will remain to
its default value of 1 and the surface will be scaled up by the
compositor to match the actual output scale, which causes blurry fonts
and widgets.

Closes #1617
