Added new option Graphic3d_RenderingParams::ToSmoothInterlacing enabled by default.
Added -smooth option to vstereo command.
Added -dpiAware option to vinit command (Windows).
Added method V3d_View::SetImageBasedLighting() for managing IBL.
OpenGl_View implementation has been revised to handle IBL updates in a more straightforward way,
Added new elliptical gradient fill method and updated vbackground command.
Renamed enum values of Aspect_GradientFillMethod and defined aliases for old ones.
Changed draw mode in OpenGl_BackgroundArray from triangle-strip to GL_TRIANGLES.
vlight command has been revised to provide more friendly syntax.
Command now accepts light index or name as first argument.
Added arguments -enable/-disable for managing enabled state.
Added argument -reset to reset light parameters to default values.
V3d_Viewer::SetDefaultLights() now sets names "headlight" and "ambient" to created lights.
Graphic3d_TypeOfLightSource enumeration values have been renamed to avoid shortcuts.
Draw::Atof(), applied corrections to avoid explicit new/delete calls.
OpenGl_LayerList::renderTransparent() - color mask is now set to write into Alpha channel of depth peeling FBOs.
OpenGl_View::blitBuffers() - avoid using undefined color for glClear(GL_COLOR_BUFFER_BIT) operation.
Added new rendering parameter Graphic3d_RenderingParams::FontHinting
allowing to enable/disable hinting (default is no hinting preserving old behavior).
Command vrenderparams has been extended with arguments -fontHinting.
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.
