Doc: NR 1.2.1 Ties - added @knownissue

This is for issue 409.

Give simple example for using whiteout to avoid ties colliding with
staff objects

Looks good.
For consistency with NR5.4.6 Painting objects white, you should subtract 4 from
each of the layer numbers, and remove the override of StaffSymbol layer.

Some people have probably used white-out on text or dynamics (in their default
layer=1) to place it over the StaffSymbol, so they depend on StaffSymbol
remaining in layer 0.

(I was wondering about this when I commented on the tracker issue, but couldn't
find the reference in the manual at the time.)

Consider moving your example from 'known issues' to the main text, maybe around
line 543.

Second Draft. Thanks Keith

Looks basically good, but could use a few alterations.
