-Support virtual text:  #7553
-- Wrong cursor position in Insert mode, wrong pos after typing char #10786
-- implement "text_align" - right
-    when not truncated, may increase line height
-- implement "text_align" - below
-    need to compute extra screen line
-- implement "text_wrap" - truncate
-- when Tab is in text handle it like a space
-- Also consider an empty line, should fix #10786.  Also check inserting text.
-- win_lbr_chartabsize() TODO item: count screen cells
-- check that when inserting/deleting text col == MAXCOL isn't changed
-- wrong cursor position (Yegappan, July 27)

-  Or Should we let the textprop highlight overrule other (e.g. diff) highlight

-  Combining text property with 'cursorline' does not always work (Billie
-  Cleek, #5533)
-- Add text property that shifts text to make room for annotation (e.g.
-  variable type).  Like the opposite of conceal.  Requires fixing the cursor
