We don't need to cover every case with a va_marshaller, but there are a
number of them that are useful because they will often only be connected
to by a single signal handler.
Generally speaking, if I opened into a file to add a va_marshaller, I just
set all of them.
This adds specific marshallers for all of the locations where a generic
marshaller is being used. It also provides va_marshallers to reduce the
chances that we get stack traces from perf going through ffi_call_unix64.
They're either wrong (when using FALSE because the widgets don't account
for changes to the CSS) or unnecessary (when using TRUE because it's the
default).

Reverts part of Commit 25b67af3
The 'width' part of the commit is the cause of #628: requisition->width
is first set to priv->layout->width, which already includes
priv->left_border + priv->right_border. It's a bit labyrinthine, but
essentially:
* layout->width is set in update_layout_size() (gtktextlayout.c line 992)
as the maximum line width, and
* the line width is set to display->width in gtk_text_layout_real_wrap()
(gtktextlayout.c line 1183), and
* display->width is set to text_pixel_width + h_margin + h_padding in
gtk_text_layout_get_line_display() (gtktextlayout.c line 2584), and
* h_margin + h_padding is the same as priv->left_border +
priv->right_border.
Adding it again leads to an increase in the size-request, which
results in wider lines; rinse and repeat.
GtkTextView scrolls to the insertion point when the text
buffer signals a paste is done. This is wrong when there
are multiple views on the same buffer, and the paste
happened in another view.
To fix this, flip the handling of the scroll_after_paste
boolean to only be TRUE if we know that we want to scroll.
It was used to mark css properties that affect widgets with text, but it
caused unnecessary invalidations. E.g. 'color' was marked as
AFFECTS_TEXT but changing just the color of a label should not
automatically queue a resize, which is what the code in
gtk_widget_real_style_updated does.
Replace this flag with GTK_CSS_AFFECTS_TEXT_SIZE and
GTK_CSS_AFFECTS_TEXT_CLIP, which GtkWidget can use only if the widget
actually has text.

Similar to GtkEntry, add an "Insert Emoji" context
menu item, and add the same keybindings. We don't
add the icon here, since it is not clear where it
would go.

Container:border-width caused the x/y coords converted to iters to be
offset inwards by that width, breaking positioning/selecting by gesture.
So, subtract :border-width in widget_to_text_window_coords(). This fixes
gesture positions, & plays fine with :margin & CSS margin/border/padding
N.B.: This is not to endorse :border-width. It’s gone in GTK+ 4 & weird
on a TextView: it’d be more intuitive to – if you must! – set it on the
TV parent. Really, please just use CSS instead. Still, it’s easy to fix.

The GTK_TEXT_WINDOW_PRIVATE enumeration value is really *not* private.
Internally, it's used as a simple "invalid value" marker, and
application and library developers are supposed to use it as such in
their own code.
Let's just document it, and since the GtkTextView documentation and
internals go a long way to state the fact that it should not be used as
an argument value, let's add some pre-condition checks as well.
This commit fixes GtkSourceView's use of GTK_TEXT_WINDOW_PRIVATE as
default value for a GObject property that was broken by the change in
glib-mkenums to honor the `/*< public >*/` and `/*< private >*/`
trigraphs.
The TextIter is passed by pointer for efficiency. We neither need to
modify it, nor should we leave it possible to accidentally do so. So,
it should be passed as a pointer-to-const.
We do not need to go through the heavyweight process of constructing a
TextLineDisplay just to get the direction out of it, when we can simply
use TextIter API to get the text and then get its direction using Pango.

Using Ctrl + left/right to skip between words, or left/right to cancel a
selection, were causing movement on the screen in the opposite direction
of the glyph on the key. This was surprising and awful UX for RTL users.
This is based on a patch covering the former case by:

adds a paragraph to gtk_text_view_get_pixels_below_lines(),
describing how it can be used together with
gtk_text_view_get_pixels_above_lines() to get the total
amount of line spacing between two paragraphs.

That would imply the pixelcache monitors the style context for changes
and it doesn't do that.
Its only use case was opacity checks, so add
gtk_pixel_cache_se_is_opaque() instead.
A problem that has been observed in polari is that links in tags
are clickable all the way into the margin. This problem is caused
by gtk_text_view_get_iter_at_position ignoring the return value
of pango_layout_xy_to_index. Instead, pass it back as a boolean
return value. This is technically an API break, but we've allowed
ourselves to change return types from void to gboolean before.
The text view draw function was leaving its cairo context
with a transformation after drawing to all the border windows,
which lead mis-drawing in gitg. Avoid this by moving the
gtk_cairo_transform_to_window call inside the existing
cairo_save/restore calls.

Derived classes like GtkSourceView with their own ::key-event
handler need access to this, in order to make their keynav
as nice as the builtin one, wrt to caret visibility.

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.
