tdf#124848 partial refactor hairline logic

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.
