Add new interfaces GetEyePosition(), GetClippingRange(), GetAspectRatio() to IVTK_IView
Add ivtkviewparams command to print current parameters of view
Add ivtkcamera comand to print current camera parameters or manages camera parameters (set ortho or persp projection)
IVtk_IShapeData::InsertCoordinate() has been replaced by IVtk_IShapeData::InsertPoint()
defining vertex position with surface normal.
IVtkVTK_ShapeData now allocates normals array within vtkPolyData.
IVtkOCC_ShapeMesher now fills in vertex positions with surfcae normals.
IVtkTools_SubPolyDataFilter has been corrected to optionally copy normals.
ivtksetboundingdraw command has been merged into "ivtksetdispmode -faceBoundaryDraw".
IVtkOCC_Shape now stores Prs3d_Drawer object used by IVtkOCC_ShapeMesher and IVtkOCC_SelectableObject.
IVtkOCC_ShapeMesher::internalBuild() made more consistent to AIS_Shape::Compute() in cleaning/triangulating shape.
Added command ivtkdefaults similar to vdefaults managing triangulation default parameters.
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.
