GtkTreeView has a particularly expensive drawing path. This can cause
issues when part of animated widget sequences. Caching the content while
a model is attached helps reduce the number of full redraws during
exposure greatly.

Some widgets have very expensive drawing paths. So caching the content
can be useful even when not scrolling.
This can help speed up widgets that are part of animation sequences and
thereby go through spurious expose events.

We were using GTkTreeView in a simple list. Also, as we know,
GtkCellRenderers are not the best way to theme and manipulate
widgets.
So instead use a GtkListBox to modernize the GtkPlacesSidebar,
and in the way clean up some parts of the code (like headings)
which were not used anymore.
Also we don't use a model anymore, since the data is simple
enough to manage it in a subclass of the row itself.
It is convenient to allow applications to show all the drop
targets at once. This improves the user experience with drag
an drop.
The new API allows the application to set the gtkplacessidebar
in a mode where invalid drop targets are insensitive and it
adds a "new bookmark" row. This mode is intended to be set
when the application is aware of a dnd operation and needs to
be stopped kwhen the application is aware that dnd operation
was cancelled or ended in a different part than gtkplacesisdebar.
The context parameter is unused in this patch, but will be
used in next patches when the sidebar will use a GtkListBox.
The reason of being unused now is just convenience.

GtkInspector is opening a separate display connection, which makes
it more likely that gtk_get_current_event() returns an event from
the "wrong" display.
We were getting ourselves in trouble by casting touch events
to GdkEventButton and poking directly at their internals. Instead,
use GdkEvent API to get what we need.
This fixes a crash when using the gear menu in epiphany with
touch. The same crash also occurred in testmenubutton.
For functions that take state flags as an argument we need to special
case the situation where the passed in flags don't match the current
state.
Previously we would create a copy of the style info, change its state
and do the lookup from there.
Now that GtkCssNode has replaced style infos, this doesn't work as well
anymore as copying a GtkCssNode is not possible.
However, unike style infos, GtkCssNodes are instant-apply, so we don't
need to copy anymore, we can just change the state of the node.
This causes some invalidations to be queued, but we can take that
performance hit as this is fallback code.

Instead of having padding outside the notebook containing
all pages, put each page in an extra box and add the padding
there. This is in preparation for allowing pages without
padding.
We can't add properties to the interface, since it breaks
3rd party implementations of the GtkFontChooser interface.
These exist, for example in gnumeric.
So, instead of a new property, add getter/setter vfuncs.
The font chooser delays creating the font description from the font face
as long as possible (it's slow). Because we use fixed height mode, we
only have to create font descriptions for rows we are actually going to
show.
This was achieved by looking at the font description column and if it
was NULL, we created a font description and gtk_list_stiore_set() it.
Unfortunately this caused a "row-changed" signal to be emitted and this
emission could happen during the cell data func.
And that caused infinite loops with accessibility when you were unlucky.
This change replaces the NULL font description with an empty one and
instead of setting the correct font description, we
pango_font_description_merge() it in. This way, the list store doesn't
change and no signals are emitted.

Due to popover modality itself, there's quite high chances the popover
stealing focus has been triggered from within, so stay friendly to it.
Hiding the popover here will only hide the grabbing popover too if this
happens.

When recoloring symbolic SVG, do not modify the original width and
height of the passed-in file; the function later will scale the image
through gdk_pixbuf_new_from_stream_at_scale(), but we should still
use the original size to create the proxy SVG, or the image will
possibly be doubly-resized or blurry.
https://bugzilla.gnome.org/show_bug.cgi?id=750605
show_or_hide_handles() tries to disable visibility when the popover is
shown, although it triggers a bit late, and lets the handles flash briefly
if both popover and handles try to show at the same time (eg. when
pressing on the selection of a previously unfocused textview, the handles
were previously hidden, so they try to show again on focus in).
The handles might fall outside the visible area, and shouldn't be shown
then. Just call gtk_text_view_update_handles() which will perform these
checks, and keep the handle conveniently hidden.
This was leading to unexpectedly visible handles (and in the
wrong/previous position, the handle code doesn't relocate the widget
it's about to hide) when "select all" was selected in the popover on
a textview needing scrollbars.
and extending the selection beyond the view above and/or below.
The check used to hide the popover if the pointed area fell partly out of
the widget allocation, textviews now can trigger that with text selections
too close to the visible edge, as a small extra area around is now reserved.
The check has been changed to only hide the popover if the pointed area
falls completely outside the widget allocation.
