With the handover of transformations to line
draw calls it is no longer feasible to detect
and prepare LineWidth stuff when the old
office definition for hairlnes is used, a
line width of zero. It was managed in the
system-independent part, but now may have to
be prepared in logic and not discrete (pixel)
coordinates. To do so, find and cleanup all
places where 1/1.0 was used as hairline line
width. Adapt all seven graphic subsystems to
handle the line width == 0/0.0 cases
accordingly. Test as good as possible.
