Layout units was introduced so we could have true WYSIWYG display.
Unfortunately it means there is a lot of duplication in the formatting
logic. You will find all through out there are things like m_iWidth and
m_iWidthInLayoutUntis, etc. This, I think, does need to be looked at at some
stage. I originally tried to have one coordinate system but found it too
difficult at the time to keep track of what units were at layout resolution
and which were at screen resolution.
The calculation of tabs in layout units still has to be completed as shown
in the following bug.
