Message:
Please review. This patch set implements the "whiteout and
whiteout-style" grob property approach.

Another approach ("whiteout and whiteout-thickness") has also been
proposed. See issue tracker:

Thanks,

Description:
Issue 4504/5 update changes.tely


Issue 4504/4 edits to tests and docs


Issue 4504/3 run scripts/auxiliar/update-with-convert-ly.sh


Issue 4504/2 convert-ly rule: whiteout-box --> whiteout


Issue 4504/1 add whiteout-style, drop whiteout-box

Introduce whiteout-style grob property, with
options of 'box and 'outline, to be used with
the whiteout grob property, and an equivalent
style property for the whiteout markup command.

Remove the whiteout-box grob property and
markup command, and use the new properties
instead.

Make the box style of whiteout the default
style again, as it was before issue 4418.
