glib will use the correct marshaller automatically. And as a side
effect, we also get all glib optimizations, like a va marshaller.

Fix s/occurence/occurrence in many places.

Avoid crashes when passing an invalid location to a
gtk_text_buffer_get_iter_at_*() function.

A first attempt added boolean return values to know if @iter has been set to
the exact location, but it breaks Python and JS bindings because the out
parameter is already a return value in those languages.

Unit tests are added.

https://bugzilla.gnome.org/show_bug.cgi?id=735341

This reverts commit a9a1c00c.

Unfortunately, adding the boolean return broke both the python
and javascript bindings, since they now return a tuple consisting
of the boolean and the out argument.

We generally use ->next directly.

Avoid crashes when passing an invalid location to a
gtk_text_buffer_get_iter_at_*() function.

A boolean is returned to know if @iter has been set to the exact
location.

Unit tests are added.

This avoids polluting the installed header with private symbols.

Following a similar change in GLib a while ago.

'bla' may by stupid, but it looks less dumb than `bla'.

This avoids pspec lookup overhead in g_object_notify.

Use g_slist_free_full more consistently. This commit just converts
the obvious cases where g_slist_forall is directly followed by
g_slist_free.

Add a ::font-features attribute to GtkTextTag, and support
font features when inserting Pango markup into a text buffer.

This commit adds the GtkTextTag:underline-rgba and :strikethrough-rgba
properties and the necessary plumbing to apply these colors in GtkTextLayout.
With this change, you can alter the color of underlines including those
of type PANGO_UNDERLINE_ERROR.

You might want to alter the underline color to differentiate between
spelling and grammer mistakes. In code editors, it is convenient to
differentiate between errors and warnings.

Note that the GtkTextAppearance struct is public ABI and has no spare
room for new fields, so we are resorting to some tricky packing to store
the colors in the unused pixel field of the fg_color and bg_color structs.
This packing is accomplished by the macros in gtktextattributesprivate.h.

This has been a very long-standing feature request.

https://bugzilla.gnome.org/show_bug.cgi?id=59390

NULL was returned in case of an empty last line. Every users needed to
special-case this. Now it will return the expected result: char_len of 0
with one PangoLogAttr.

In compute_log_attrs(), 'paragraph' will be the empty string "" with
'char_len' == 0.
pango_get_log_attrs() works fine with an empty string, it will return
one correct PangoLogAttr (because there is one text position for the
empty string).

It fixes the unit tests for gtk_text_iter_is_cursor_position().

- only one blank line is enough to separate code sections.
- the 'signals' variable was in the middle of function prototypes.
- compare pointers to NULL in some conditions ("if(blah) should be used
  only if blah is a boolean variable). It makes the code clearer.
- various other things.

g_memmove() is deprecated, it is a simple macro that just calls
memmove() with the same parameters.

Reviewed by Paolo Borelli on IRC.

Although there is the "changed" signal, it is more correct to notify the
"text" property too. It can be useful for a small text view, where the
text is saved e.g. to gsettings with a binding to the text property.

The "text" property includes only the text, not child widgets or images,
so the notify signal is sent too many times (also for child widgets and
images), but it's not a big problem.

GSlice is better for allocating structs.

This is expected to happen on wayland and other platforms with no primary selection,
and just leads to the selected text being cleared after any attempt to change the
text selection itself through either mouse/keyboard.

Returns NULL in case of a duplicated tag name in the tag table. It is
still a programmer error to duplicate a name, but if it happens the
behavior is a little nicer (and hopefully doesn't crash).

Instead of Return value:

It is a little heavy handed. The text can speak for itself.

It didn't explain the behavior when there is a non-empty buffer
selection.

https://bugzilla.gnome.org/show_bug.cgi?id=339539

It is more logical to first delete the selection and then pasting the
text. When the selection and the text contain tags, the new behavior is
more natural.

A segfault in paste_from_buffer() is also avoided. The segfault occurs when
the text to paste is deleted because it is the selection.

https://bugzilla.gnome.org/show_bug.cgi?id=339539

Move GtkWrapMode from GtkTextTag to the GtkTextView section. The wrap
mode property is in the text view.

Links to the "mark-set" and "mark-deleted" signals.

Add a precision about gtk_text_buffer_get_iter_at_line().

Fix typo in gtk_text_tag_set_priority().
