Use U+00D7 MULTIPLICATION SIGN and U+200A HAIR SPACE instead of plain
old 'x' and ' ', following https://wiki.gnome.org/Design/OS/Typography.
Sadly, many fonts don't have space variations, so Pango/harfbuzz fall
back to using the regular space glyph anyway.
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().

For functions using _gtk_text_buffer_get_line_log_attrs():
- gtk_text_buffer_backspace()
- some gtk_text_iter functions (word/sentence/cursor boundaries)
As the FIXME comments show, there is a bug with
gtk_text_iter_is_cursor_position() for an empty last line.

There was some confusion between unflipped and flipped positions.
Both final_position and current_position are meant to be unflipped,
and get_effective_position() needs to be applied to them to get
a flipped position. _gtk_window_set_popover_position() also expects
an unflipped position.

This was introduced as a hackish way in 3.6 to make font updates
propagate properly. But since then, font handling has been changed and
this flag is no longer necessary.
gtk_style_context_invalidate_internal() will respect only the current
saved state of the style context, which is wrong when updating the scale.
In that case, the whole style context needs updating.
- 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.
This is a hack to get around the optimizations done by the CSS engine.
The CSS engine will notice that no CSS properties changed on the
widget itself when going from one state to another and not queue
a redraw.
And the reason for no properties changing will be that only the
checkmark itself changes, but that is hidden behind a
gtk_style_context_save()/_restore() pair, so it won't be caught.
