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.

When a RTL paragraph is not set to wrap, the right margin is not respected
because of the margins counted twice so we replace
display->width by PIXEL_BOUND (extents.width), the same quantity
without the margins.

In add_preedit_attrs, don't free foreground/background colors already
set in the underlying text attributes (style). They will be free'd by
release_style.

Move the handling of primary/secondary cursors to gtktextdisplay, which
makes code simpler and more consistent to how GtkLabel and GtkEntry
draw cursors, which is useful in preparation to further refactoring.

This now allows text view to render text with alpha values in
the text foreground and backgrounds, the work is almost complete,
currently the error-underline-color is still a GdkColor style property
and since we use only GdkRGBA for rendering it needs to be converted
and applied, probably a new rgba version of the style property should
also be introduced.
This commit adds tests/testtextview that must be run from the tests/
directory to show translucent text in action.
It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
Especially the gtk_*_type ones in gtktexttypes.h were mentioned in
gtk.symbols presumably by accident. That header isn't even installed,
so no way can they be supposed to be public.
gtk_text_attr_appearance_type is from the installed but "semi-private"
gtktextlayout.h, so drop that one too from gtk.symbols for now.
The use of gtk_text_unknown_char_utf8 is bit of a mess. Code in a few
files knew implicitly that it is three bytes. Define a symbolic name
for the length of it instead. Add an exported function
gtk_text_unknown_char_utf8_gtk_tests_only() that returns a pointer to
it just for the sake of gtk/tests/textbuffer.c. Prefix the variable
with an underscore.
I doubt the usefulness of the test_utf8() in textbuffer.c. If it could
be dropped, gtk_text_unknown_char_utf8_gtk_tests_only() could be
dropped, too.
This commit was created using a script that searched for all docstrings
containing a parameter and the string 'or %NULL'.

The Gtk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GTK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.

Bug 567468 – no check for trailing != NULL in
gtk_text_layout_get_iter_at_position()
* gtk/gtktextlayout.c: (gtk_text_layout_get_iter_at_position):
Check for trailing to be non-NULL.
* gtk/gtktextview.c: (gtk_text_view_get_iter_at_position): document
that trailing may be NULL.

* gtk/gtktextlayout.c: (gtk_text_layout_get_line_display),
(get_style): do not call _gtk_text_btree_get_iter_at_line() and
_gtk_text_btree_get_tags() for every segment, instead call them
once and then collect the tags while iterating over the segments.
(get_tags_array_at_iter), (tags_array_toggle_tag): new functions
for tags array handling.

Avoid recreating pangolayouts in GtkTextView on cursor movement
(#435405, Behdad Esfahbod).
* gtk/gtktextlayout.c:
* gtk/gtktextlayout.h: new GtkTextLayout method invalidate_cursors(),
and functions gtk_text_layout_invalidate_cursors() and
gtk_text_layout_cursors_changed(), to use when invalidation is due
to moved marks or changed selection.
* gtk/gtktextbtree.c:
* gtk/gtktextbtree.h: use what's appropriate when invalidating layout.
* gtk/gtk.symbols: add new functions.
* README.in: added a note about changed GtkTextLayout API.
