Now on property panel there is option 'Coarse View' which allows to set
selected drawing view's Hidden Line Removal to utilize polygonal algorithm.
This should be faster on same cases (complex models).
When this option is set for a view there is known limitation with dimensions not
working on this experimental mode. At least currently this is best utilized on
view with no dimensions.
Also the vertices' 'black dots' are not drawn on this mode view to avoid
cluttering. Face hilite is avoided, to gain speed. All curves are represented
by short linesegments in this mode.
Previously TechDraw always used OCC's exact HLR algorithm to generate views,
which produces good quality and continous shape lines but is sometimes
slower to generate than with polygonal approach.
Additionally now there is bool 'CoarseView' Parameter Editor setting, if anyone
wants to set this as their default.
