Instead of drawing text for selections and links manually, use the
gtk_render_background() and gtk_render_layout() functions.
As a side effect, this allows shadows on selected text and links
and real backgrounds (like gradients or images), too.
Since it turns out that x/yalign can't be quite equivalently
replaced by h/valign, bring them back as label properties, so
we can eventually get rid of GtkMisc.

When links are entirely hidden in an ellipsis, don't let
them be activated by clicking and skip them when moving
the focus around.
This commit depends on enhancements in pango 1.36.7 which
make it possible to find the ellipsed runs in a PangoLayout.
With older pango, things will work the same way as before.

GtkGestureSingle::button is set to 0 on the multipress gesture, as several
buttons are managed by that gesture. Also avoid some extra lines of code
setting what nowadays are default values.

The previous code for computing the clip rectangle forgot to respect
the text-shadow CSS property. This is usually not very visible because
text shadows usually don't extend the ink rectangle by very much.
See attached testcase for an example.
Otherwise, the CSS background we draw would be clipped if the ink rect
was smaller than the allocation (a very common thing).
Broken since 37030a7710 where we clipped
to the ink rect.
A multipress gesture takes care of link handling, and char/word/all
selection mode on selectable labels. A drag gesture is used for both
text selection and DnD checks on selectable labels.
Go back to respecting GtkMisc::xpad/ypad. Not doing so breaks
the misc-alignment reftest. As long as we still derive from
GtkMisc, we may as well do this.
We see an active link when creating the menu, but by the time
the menuitem is activated, we've received a leave notify that
makes the label clear its active link. Instead, give the
menuitems a direct reference to the link that is active when
the menu is created.

gnome-terminal is still using this setting, so we'll let
applications override it for another cycle. It is no longer
backed by a system-wide setting, though, and it will still
go away eventually.

We should only eat button release events when the label is
actually selectable, since the comment indicates that we
want to eat the release events belonging to press events
that triggered a selection. This fixes problems with actions
on parent widgets that are triggered by button release,
as seen in this bug:

Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
