0028895: Visualization, V3d_View::SetComputedMode() - HLR calculation is performed multiple times when 'hlr on' has been called

Browse Source 
V3d_View::SetComputedMode() - removed implicit View update.

Graphic3d_CView::SetComputedMode(), ::ReCompute() - fixed
uninitialized bounding box of Computed structure.

PrsMgr_Presentation::Compute() - fixed computation of Computed structure
with transformation within Connected presentation.

StdPrs_HLRPolyShape::Add() now creates Graphic3d_ArrayOfSegments instead of
inefficient Graphic3d_ArrayOfPolylines with boundaries at every segment.

Fixed error in test case bugs/vis/bug24388_1.
