Summary0025970: Shape Healing - enable parallel reconstruction of pcurves
DescriptionAs reported e.g. in 0022598:0034439, it is typical that most of the time of data translation from STEP is taken by reconstructing pcurves (projection). This operation can be easily run in parallel, as pcurve is generated independently for each edge (there is some dependency however through evaluating the same surface, this should be resolved by 0024682 if each thread uses its own surface adaptor).

See ShapeFix_Wire::FixEdgeCurves() as the main function. Note that apart of pcurve projection, SameParameter operation can also take considerable time and may deserve paralleling.

The parallel execution should be enabled by some option available in ShapeFix_Wire and also in DE resource files (see ShapeProcessAPI).
