Instead of having old and new style, now have a GtkCssStyleChange opaque
object that will compute the changes you are interested in for you.
This simplifies change signal handlers quite a bit and avoids lots of
repeated computation in every signal handler.
Use the text CSS node for rendering text, and the selection node
for rendering selected text, avoid gtk_style_context_save, update
states of all CSS nodes, and use the proper states when querying
style properties.
Use a CSS node with name selection, like we do for entries
and labels. Unlike those widgets, we currently don't user
gtk_render_background, but just use the background color.
That will require more effort.
When I added the draw_layer vfunc it accidentally got passed a cairo_t
that was configured with to draw in the viewport coordinate space (rather
than the buffer coordinate space). This makes things unnecessary complex,
because you have to convert between the two.
The pixel cache is shared between the text and the layers, so there is
no way to use draw_layer to get a stationary overlay effect. Thus it makes
much more sense for the draw_layer vfunc to draw in the buffer space.
Just changing this would break ABI for existing code, so this is fixed
by adding new layer types and deprecating the old ones.
Also, we use the new layer types to fix gtk3-widget-factory.

Otherwise the popopver will be automatically unmapped in
_gtk_popover_update_child_visible() when the X axis (coming more
or less directly from events) goes outside the textview.
We are passing widget coordinates to gtk_text_view_window_to_buffer_coords()
which expects coordinates to be relative to the text window in this case.
This may result in drop coordinates being displaced if the side windows to
the top/left sides are visible and taking space, so the DnD indicator will
point to the wrong position.
This can be seen on gnome-builder and gedit when displaying line numbers.
These days exposure happens only on the native windows (generally the
toplevel window) and is propagated down recursively. The expose event
is only useful for backwards compat, and in fact, for double buffered
widgets we totally ignore the event (and non-double buffering breaks
on wayland).
So, by not setting the mask we avoid emitting these events and then
later ignoring them.
We still keep it on eventbox, fixed and layout as these are used
in weird ways that want backwards compat.
This changes textview to share the style context with the pixelcache.
Doing so allows pixel cache to optimize the surface creation and use
a CAIRO_CONTENT_COLOR instead of CAIRO_CONTENT_COLOR_ALPHA when
appropriate.

Same as we did for the entry in the previous commit.
Previously, we just hid the cursor if a key event was adding text,
but not when you used backspace, or Ctrl-V. Rearrange things so that
we obscure the cursor whenever the buffer contents change while we
are handling key events.

The purpose of this patch is to fix regressions in GtkTextView
scroll behaviours due to commit d138156.
( addition of padding and margins to the view )
Adding some padding is done by, for example, in inspector css tab with:
GtkTextView {
padding: 10px 10px 10px 10px;
}
and adding margins, by changing one of *-margin properties
( * standing for left/right/top/bottom ) or the corresponding
accessor functions.
Understand that none of these bugs are easy to trigger.
What's happened is that a old and wrong version of the code of the code
( lost in the mean time ) was pushed.
These bugs are best seen with wrap mode set to off.
The commit 8baab8f fix a first regression.
This one is about:
- Cursor going out of the view at line ends instead of being visible
or triggering the horizontal scroll.
- Padding not displayed correctly
when moving cursor at beginning/end of lines
- When horizontal scroll position not at left, cursor can make scroll
by more than one character (you need left padding to see this )
- Moving the cursor arround, the rendered text can be shitted in x or y.
( fixed by converting adjustment float values
to integer before calculations )
It can be observed by going down with the cursor more
than the view height then going up
- retval return value of _gtk_text_view_scroll_to_iter wrong in some cases
In addition, this patch re-factor priv->top_border
in screen_dest.y calculation
Of course, all GtkTextView and GtkSourceView based app were impacted
by these bugs ( gedit for example, see bug 754147 )

When you move line by line, only padding is
automaticly shown and you need to use Page key to show margin.
This commit also fix cursor going out of the screen bug.
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 buttons on the popover where stealing the focus from the text
view on click, causing the popover to be dismissed before the action
was taken. Fix this by making the buttons not take focus on click.
Use the drag-started signal to differentiate between drags that
move a handle and taps on a handle. Show the touch selection popup
for the latter, but not the former.
Hide the handles when the popover appears, and brind them back
when it disappears. This will need revisiting if we start using
the popover for mouse interaction as well, where we may not
want handles to show up.
We don't want the popover to appear spontaneously, so eventually
the timeout may go away altogether. For now, shorten it to 50ms,
to avoid rewriting all the places where the timeout is set or
unset.
Update style for touch selection in GtkEntry and GtkTextView
according to https://wiki.gnome.org/Design/OS/Selections
Add 'Select All' to the default actions, change actions
to use icons and move the popover to the bottom. If there is
no selection, just offer to paste.
Text insertion/pasting might trigger scroll, so we'd have to wait
until the text was revalidated and the scrolling truly happened
before we can check the new handle(s) position.
Just use the last coordinates given on XdndPosition/drag_motion() in
order to trigger scrolling.
When running on Xwayland, the pointer position is unknown at this
stage on the X11 side, so the coordinates given here are bogus.
This change avoids both roundtrips and this situation.
