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.
Added new class AIS_ViewCube implementing interactive cube
displaying orientation of the main axes of the model space in the viewer.
Each side, edge, or corner of the cube corresponds to particular orientation of the camera,
and the class provides methods to move the camera to corresponding position (with animation if needed).
AIS_InteractiveContext::LastActiveView(), added new property returning the last View processed by MoveTo() event.
AIS_InteractiveContext::BoundingBoxOfSelection(), added method returning bounding box of selected objects.
SelectMgr_EntityOwner::HandleMouseClick(), added new callback for handling
mouse clicks by owner itself without automatic highlighting and clearing previous selection.
Called by AIS_InteractiveContext::Select() method.
AIS_ViewController::ViewAnimation() has been extened with camera animation propery,
which can be bound to AIS_ViewCube for smooth embedding into event loop.
Prs3d_ToolDisk has been extended with parameters specifying angle range.
Graphic3d_MaterialAspect now initializes all coefficients to 1.0
when Graphic3d_NOM_UserDefined is passed to class constructor.
AIS_AnimationCamera::update() now sets the end camera position if animation duration is 0.
Prs3d_DatumAspect, added missing setters.
New command vviewcube has been added.
