OpenGl_Caps::buffersOpaqueAlpha is now set to TRUE by default.
OpenGl_View::runPathtrace - fixed higlighting with PathTracing turned on and buffersOpaqueAlpha=true.
Fix incorrect value of axis intersection with segment inside of SelectMgr_AxisIntersector::raySegmentDistance().
Move camera definition to base intersector (it is not possible to set it for axis intersector, is is not applicable).
Add method Graphic3d_Camera::SetIdentityOrientation() to set camera parameters to make current orientation matrix identity one.
Remove all matrices from selection intersectors and frustum builder and use camera instead of them.
Fix missed axis tests in vselect grid.
Fixed regression of SelectMgr_ViewerSelector::SetPixelTolerance(). Removed redundant myToUpdateTolerance flag.
SelectMgr_AxisIntersector::raySegmentDistance() - fixed usage of SquareModulus() instead of Modulus().
SelectMgr_ViewerSelector::TraverseSensitives() now skips both BVHSubset_2dPersistent and BVHSubset_3dPersistent relying on Camera.
AIS_ViewController::handleXRMoveTo() now uses interface for picking by Axis explicitly
instead of emulating axis by point picking.
Extrema_GenExtCS.cxx: subdivision on intervals for periodic c curves is added
Extrema_FuncExtCS.hxx: access to fields mySqDist, myPoint1, myPoint2 is added
bug32225: new test case is added
Removed testgrids 'bugs/vis' and '3rdparty'; tests have been redistributed across other grids.
Moved testgrid 'v3d/ivtk' into dedicated 'vtk/ivtk'.
Added testgrid 'vselect' dedicated to 3D viewer picking/selection functionality
and filled with tests from 'v3d/vertex', 'v3d/face' and similar groups.
Added testgrid 'opengl' dedicated to OpenGL driver low-level functionality (GLSL programs and similar)
and filled with tests from 'v3d/glsl', 'v3d/raytrace', '3rdparty/fonts', 'bugs/vis' (portion) and similar.
Added testgrid 'opengles3' dedicated to OpenGL ES 3.0 driver low-level functionality
and reusing tests from 'opengl' testgrid.
Subgroup 'opengles3/raytrace' is disabled on Windows, as Ray-Tracing currently requires OpenGL ES 3.2.
while ANGLE library implements only OpenGL ES 3.0.
Added testgrid 'opengles2' dedicated to OpenGL ES 2.0 driver low-level functionality
and reusing a limited subset of passing tests from 'opengl' testgrid.
Currently testgrid is activated only on Windows platform when using ANGLE library
(properietary OpenGL ES drivers do not allow creation of restricted 2.0 context).
Test cases have been cleaned out to put bug description into log,
to properly load necessary plugins and to explicitly dump viewer.
