Doing reset() on the text widgets after commit and delete_surrounding
is still too eager for some IMs (e.g. those that expect being able
to commit text while keeping a preedit buffer shown).
However, reset() is more of a "synchronize state" action on Wayland,
and it is still desirable to do that after changes that do come from
the IM (e.g. requesting the new surrounding text and cursor/anchor
positions). Notably here, the text_input protocol may still come up
with a preedit string after this state synchronization happens.
Shuffle the code so that the text widgets do not reset() the IM
context after text is deleted or committed, but the Wayland IM does
apply its practical effects after these actions happen. This keeps
the Wayland IM fully up-to-date wrt text widget state, while not
altering the ::commit and ::delete-surrounding-text behavior for
other IM context implementations.
When the IM commands the GtkText to delete text, the cursor position
would change, and so would the surrounding text. Reset the IM context
so that these updates are properly picked up by the IM.
Fixes backspace key behavior in the GNOME Shell OSK, since that relies
on the surrounding text being properly updated for the next iteration.
Resetting the IM on IM updates is too eager and indeed the simple
IM context doesn't like that this happens in the middle of dead
key handling.
We however want to reset the IM after actual text buffer changes
(say, a committed string) moved the cursor position, altered the
surrounding text, etc. So that the IM implementation does know to
update its state.
Since there is going to be an actual IM reset anyways, it does
no longer make sense to try to preserve the old priv->need_im_reset
status during commit handling.
During text widget manipulation (inserting or deleting text via keyboard)
the IM context is reset somewhat early, before the actual change took place.
This makes IM lag behind in terms of surrounding text and cursor position.
Shuffle these IM reset calls so that they happen after the changes, and
ensure that the IM is actually reset, since that is currently toggled on
a pretty narrow set of circumstances.
Also, fix a bug during GtkEventControllerKey::im-update where the condition
on cursor position editability to reset the IM context was inverted.
The size of the cursor depends on either the gtk-cursor-aspect-ratio
GtkSetting or as of the previous commit on the GtkSetting or the
cursor-aspect-ratio style property. GtkTextView was only considering the
style property.

The 'select-all' signal requires a boolean argument to specify
whether to select all or none. So explicitly pass TRUE to select
all text instead of letting the demons choose one for us.
When making changes above the current visible region, we might need to
invalidate the pixelcache as the Y positions will no longer match. This
usually is not needed because changes are made interactively and are made
onscreen.
Other cases, though, can include an application changing the first line
of the buffer automatically. We lose the ability to pixelcache well in
this scenario, but that is unlikely an issue since rapid Y geometry resize
or scrolling is less likely to be occuring. For situations where this is
an issue, you can avoid removing the \n from the buffer so line heights
are uneffected.

It's currently used only to not include the insert emoji option in the
context menu, but it's still possible to show the emoji chooser in both
GtkEntry and GtkTextView using the key bindings.

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:

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.
