8282698201 textview: Use paintables instead of textures, and fix the support
This changes gtk_text_buffer_insert_texture() to
gtk_text_buffer_insert_paintable() which is strictly more useful
(as textures are paintables). It also fixes the code to actually
support drawing the paintables (as well as tracking changes
to the paintables.

3ec2d5fa38 Zero-fill new GtkTextIter
iter_init_common() is used on uninitialized GtkTextIter, and since neither it
nor its callers initiliaze its padding fields, they contain garbage.

This is a problem for Go - which checks that structs passed to C functions do
not contain pointers to Go-allocated memory - when the garbage happens to be
such a pointer.  Although Go zero-fills all GtkTextIter that it allocates, this
does not help when GTK functions such as insert_pixbuf_or_widget_segment called
for gtk_text_buffer_create_child_anchor copy garbage from their stack-allocated
GtkTextIter into a clean iter.  To work around this a GtkTextIter has to be
discraded after use in text buffer anchor inserting functions:

This affects a few apis, such as gtk_text_iter_get_pixbuf,
gtk_text_buffer_insert_pixbuf and GtkTextBuffer::insert-pixbuf,
which have all been replaced by texture equivalents.

aa48399002 textiter: fix bug in gtk_text_iter_backward_line()
gtk_text_iter_backward_line() checks the value of
real->line_char_offset without previously calling
ensure_char_offsets (real) to make sure the former
is up-to-date.

As a consequence of this, when gtk_text_iter_backward_line()
is called after a gtk_text_buffer_insert_range() in the
first line of buffer, the iter is not moved to the start of
the line, and the return value is wrong.

Fixed by adding the ensure_char_offsets() call.

A test case for this bug is added to the textiter gtk testsuite.

745c348ff8 Make GtkTextAttributes private
This is a problematic struct, and giving direct access to it
has kept us from making improvements to GtkTextView. Drop it
from the public API, together with the auxiliary APIs. If
it turns out that this functionality is needed, we should add
individual getters.

1dcb3a0f88 textiter: add starts_tag() and deprecate begins_tag()
The name gtk_text_*_begins_* was used only for begins_tag(). All other
similar functions use "starts": starts_line(), starts_word(), etc.

So for consistency, add gtk_text_iter_starts_tag() and deprecate
gtk_text_iter_begins_tag().

Also change (allow-none) to (nullable), to use the new annotation.

1a8f3e2462 textiter: fix bug in case insensitive backward search
'win.lines' contains the same content as the GtkTextBuffer, so to find
@match_start, forward_chars_with_skipping() is called with
skip_decomp=FALSE (the last parameter). So far so good.

On the other hand, the content 'lines' (the needle split in lines) is
casefolded and normalized for a case insensitive search. So,
forward_chars_with_skipping(..., skip_decomp=TRUE) must be called only
for the portion of text containing the needle.

Since 'start_tmp' contains the location at the start of the match, we
can simply begin at that location to find the end of the match.

Unit tests are added.

b23eabbd64 textiter: fix bug in _gtk_text_btree_get_iter_at_last_toggle()
If the last tag toggle is the end iter, the function returned the wrong
tag toggle.

This resulted in some bugs where the view wasn't relayout/redrawn
correctly.

The function also always returned TRUE, probably because the return
value is used nowhere. But for consistency with
_gtk_text_btree_get_iter_at_first_toggle(), it's better to keep the
return value, and also because otherwise the function would be wrong (it
doesn't always return a tag toggle, if there is none).

706c8e9c8d Simplify _gtk_text_buffer_get_line_log_attrs()
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().

f39d211021 GtkTextView: various code clean-ups
- 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.

dc1317a521 textiter: fix bug in find_visible_by_log_attrs()
find_by_log_attrs() can return true only in this case:
return moved && !gtk_text_iter_is_end (arg_iter);

So if the iter moved (i.e. something has been found), but is the end
iter, find_by_log_attrs() returns false.

Now the same checks are made in find_visible_by_log_attrs(). The public
functions using find_visible_by_log_attrs() say in their documentation
that false is returned for the end iter, hence the check with
gtk_text_iter_is_end().

69d20f53e2 textiter: fix bug in FindLogAttrFunc functions
attrs[len] is the last PangoLogAttr available, at the iter position after the
last character of the line.

For a line in the middle or the start of the buffer, the '\n' is taken
into account by 'len'. For example the is_word_end is generally reached
before the '\n', not after. But for the last line in the buffer, where
there is no trailing '\n', it is important to test until attrs[len].

The bug didn't occur before because find_by_log_attrs() worked directly
on the iter passed as the function argument. But now it is no longer the
case.

76f3866bd3 textiter: make the FindLogAttrFunc functions clearer
- Return true (found) and false (not found) explicitly.
- Set found_offset only when something has been found.

find_backward_cursor_pos_func() was a bit different, the while loop had
the condition "offset > 0" but the return was "offset >= 0". Probably a
micro-optimization, since offset == 0 is always a cursor position.
Anyway now the code is the same as the other functions.

472fd9a75f textiter: small optimization for find_by_log_attrs()
Use gtk_text_iter_set_line_offset (&tmp_iter, 0) instead of
gtk_text_iter_get_line(). The difference should not be big. In the first
case the line doesn't need to be traversed thanks to the offset 0. For
get_line(), the btree must be traversed.

A temporary iter is needed to not break the behavior. But the behavior
is quite strange, the function works directly on the iter passed as an
argument to the function, even if the function returns FALSE (not
found). So maybe a later commit will fix this strange behavior.

7f6ae622d3 textiter: remove recursivity of find_by_log_attrs()
find_by_log_attrs() was a recursive function. It is replaced by an
iteration.

The already_moved_initially parameter was TRUE only for the recursive
call, so the paramater is removed.

There is also a small cleanup of the find_visible_by_log_attrs()
(remove trailing spaces, fix indentation).

There is still a part to optimize for a later commit.

22ce03fd94 doc: improve documentation of gtk_text_iter_inside_word()
There is a possible confusion with the sentence:
"@iter is inside a natural-language word"

The iter should be viewed here as the pointed character (i.e. on the
right of the iter), not as a position between two characters.

Instead of improving the documentation, another solution would have been
to change the implementation so it is interpreted as an iter position
inside a word, i.e. between two characters that are part of a
natural-language word. But maybe some applications rely on the current
implementation.

ea4e88df86 textiter: bug fix in forward_search() and backward_search()
When the search is case sensitive, g_utf8_normalize() is not called, so
the skip_decomp argument of the function forward_chars_with_skipping()
must be FALSE.

To verify that, when searching "éb", the count parameter of
forward_chars_with_skipping() have a different value:
- case sensitive: count = 2
- case insensitive: count = 3 (g_utf8_normalize() has been called)
