This adds a line-height property to GtkTexttag and a
line_height field to GtkTextAttributes, and translates
it to a pango attribute.

We need to render even an empty paragraph when
it has a block cursor at the end. This fixes block
cursors not showing up in empty lines.

4a0d3d7acc docs: Reduce redundancy 
Remove a boatload of "or %NULL" from nullable parameters
and return values. gi-docgen generates suitable text from
the annotation that we don't need to duplicate.

This adds a few missing nullable annotations too.

d719a3d877 textbtree: Return tags in a GPtrArray

copying the array in one place, and generally makes
for better code.

a75c038e09 textview: Tweak render nodes 
Arrange for the contents to be in a single transform
node that is updated as we scroll. This makes the job
of the render node differ a lot easier, since it does
not have to compare to big containers one-by-one.

9be2f130f0 textview: Fix blinking block cursors 
When we have a block cursor, we need to discard the
cached node of the line containing the cursor, in order
to get a blinking cursor.

3a928c8980 textlayout: Render cursors at the end 
Don't place the insertion cursor render nodes in the
middle of the text nodes for all the text. This helps
the renderer batching the text draw calls together.

anyway.

98b99201b0 gskpango: Remove bounds rect 
We only need this to render shapes and trapezoids, i.e. only when
falling back to cairo. Remove code to measure the layout and convert the
ink_rect to a graphene_rect_t from gtk_snapshot_append_layout() and do
it when drawing shapes and trapezoids instead.

c09575d9cb textlayout: Avoid some iter comparisons 
We were doing more iter comparisons than necessary in the
inner loop of gtk_text_layout_snapshot(), in the presence
of a selection. Rewrite the code to compare line numbers
instead, which is faster than full iter comparisons.

35325ea11a linedisplaycache: improve invalidation with y_range 
When we invalidate a y_range using the common pattern of y==0 and
old_height==new_height, we are generally invalidating the entire buffer.

This short-circuits that case to just invalidate the buffer in a faster
and more complete form. The problem here appears to be that we can't
always calculate the ranges properly to invalidate because validation
has not run far enough.

fae014eb45 textlayout: remove virtual table indirection 
GtkTextLayout is private now and therefore we can drop all of
the indirection through the class vtable. Instead, just call the
implementations directly and remove the unused vtable entries
for default signal handlers.

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.

9c2c5665df textview: Render visible marks better 
The only other visible mark that is in common use
besides insert and selection_bound is dnd_mark, and
we don't want it to blink or be affected by 'cursor'
visibility.

Therefore, cache not just the cursor positions, but
also whether they are insert or selection_bound,
and take that into account when rendering them.
