A new command vbackground is created. Old background commands are made aliases for the newly created command (including vsetdefaultbg).
Tests are modified using newly added command vbackground.
AIS_Manipulator crashes on SetPart method when 2 inputs (AIS_ManipulatorMode, Standard_Boolean) has been fixed up.
Test case for this bug has been added.

now includes program Id within error log.
OpenGl_ShaderManager now supports mapping texture onto point primitive within built-in programs
(texture transformation is ignored).
testdiff now looks for "IMAGE_COLOR_TOLERANCE: Tol" statements in log
to execute diffimage with -toleranceOfColor Tol parameter.
Image difference is first performed with 0 tolerance and then optionally with non-zero tolerance,
so that the log always includes information that some images are different,
but with two different messages:
- "IMAGE differs" for images failed comparison;
- "IMAGE is similar" for images passed comparison only with non-zero tolerance.
v3d/materials - disabled MSAA and removed duplicate.
demo/samples/materials - compare screenshots with 0.8% color tolerance (2/255).

Improved parsing of ZLayer names within vdisplay, vzlayer and vselprops commands.
vreadpixel now reports syntax errors on wrong input.
Added new flag Graphic3d_AspectFillArea3d::ToDrawSilhouette() activating silhouette (outline) rendering.
The new feature can simulate fake HLR look-n-feel,
when combined with Aspect_IS_HIDDENLINE interior style (filling object with background color),
face boundary edges (with most continuity flag set to c2 or lower).
Silhouette GLSL program is very simple - it displaces model alongside vertex normal,
so that it is applicable only to smooth surfaces and closed volumes,
and produces visual artifacts at sharp corners, especially when face boundary is disabled.
OpenGl_SetOfShaderPrograms has been modified so that to reduce
dimensions of the grid of static size based on amount of program combinations.
OpenGl_PrimitiveArray no more allocates VBO resources if primitive array
is marked to be not drawn via interior style / line type / marker type.
A new flag Prs3d_Drawer::FaceBoundaryUpperContinuity() has been introduced
handled by StdPrs_ShadedShape::FillFaceBoundaries() method to exclude edges
of higher continuity class (e.g. to skip seam edges).
Draw Harness command vshowfaceboundary has been replaced by vaspects:
> vaspects -setFaceBoundaryDraw 1 -setFaceBoundaryColor RED -setFaceBoundaryType DASH.
Aspect_IS_HOLLOW now an alias to Aspect_IS_EMPTY and Aspect_IS_HIDDENLINE does not implicitly enables mesh edges,
so that Graphic3d_AspectFillArea3d::SetDrawEdges() should be set independently.
OpenGl_ShaderManager now provides built-in GLSL programs for drawing mesh edges
in single pass (and on OpenGL ES which does not provide glPolygonMode()).
Graphic3d_RenderingParams::ToEnableAlphaToCoverage is now enabled by default
and properly handled at TKOpenGl level - enables coverage for Graphic3d_AlphaMode_Mask primitives.
OpenGl_PrimitiveArray now uses GLSL programs instead of glPolygonMode() by default,
which can be managed by OpenGl_Caps::usePolygonMode flag (desktop OpenGL only).
glPolygonMode() is also used as fallback regardless OpenGl_Caps::usePolygonMode flag
when GLSL programs are not supported (Geometry Shaders are required)
or stipple line style is required (not implemented within Face GLSL).
vaspects command has been extended by -setInterior -setDrawEdges -setEdgeColor -setEdgeType -setEdgeWidth
arguments replacing vsetinteriorstyle/vsetedgetype/vunsetedgetype commands.
vaspects now accepts arguments without "set" prefix.

Redundant command BUC60738 has been removed.
AIS_ColorScale - fixed usage of uninitialized FillArea aspects.
The problem when object transformation was applied to the bounding box twice has been fixed in OpenGl_Structure.

OpenGl_ShaderManager - added new GLSL sub-programs for clipping plane chains.
Bnd_Range::TrimFrom(), ::TrimTo() - added auxiliary methods for trimming the range.
SelectMgr_ViewClipRange now handles non-continuous clipping range.
Graphic3d_SequenceOfHClipPlane now aggregates NCollection_Sequence instead of inheritance.
OpenGl_CappingPlaneResource - triangulation has been adjusted to make front face following CCW order.
Introduced new method AIS_InteractiveContext::ClearDetected() allowing
to reset the list of detected objects and clear dynamically highlighted
entity under mouse cursor after previous AIS_InteractiveContext::MoveTo().
vmoveto command has been extended with new argument -reset.
While UV Iso parameters are obtained in StdPrs_Isolines, UV limits should be applied only if face bounds has infinite values.
In the issue case, the UV values are greater than UVLimits and not infinite. This fix makes possible to have correct Iso lines in presentation without modification of UV limits beforehead.
Graphic3d_AspectFillArea3d has been extended by new property ::ShadingModel(),
which is set to Graphic3d_TOSM_DEFAULT by default.
The new API allows assigning Shading Model to specific Primitive Array groups
instead of entire Viewer, which was the only possibility before.
Graphic3d_TypeOfShadingModel has been extended with Graphic3d_TOSM_DEFAULT value
meaining that Shading Model defined as default for the Viewer should be used.
Graphic3d_TOSM_NONE has been renamed to Graphic3d_TOSM_UNLIT.
Documentation of Shading Models has been improved by more details.
V3d_TypeOfShadingModel enumeration has been merged into Graphic3d_TypeOfShadingModel
avoiding duplicated definitions and confusion.
Old values has been left for compatibility with old code and can be marked deprecated in future.
Draw Harness command vaspects has been extended by new argument -setShadingModel
for testing Shading Models assigned to entire objects.
OpenGl_SetOfShaderPrograms now holds an array of Shading Models.
OpenGl_ShaderManager interface has been modified and now requires enumeration as input
in several places where Boolean flags have been used previously
(methods ::BindFaceProgram(), ::BindLineProgram(), ::BindMarkerProgram()).
OpenGl_Workspace now defines default (undefined) OpenGl_AspectFace as Graphic3d_TOSM_UNLIT
to simplify indication of primitive groups with undefined Fill Area aspects,
and so that Graphic3d_TOSM_UNLIT set as default Shading Model will not make artifacts on Lines and Markers.
AIS_Manipulator::Axis::Compute() - added missing initialization of Fill Area aspects (leading to undefined behavior).
Graphic3d_CLight is now defined as a class inheriting Standard_Transient,
so that it's fields now should be accessed through methods.
Graphic3d_CLight::IsEnabled() - new property allowing to disable light source everywhere.
Confusing alias OpenGl_Light has been removed.
Graphic3d_CLight::SetAttenuation() - the upper limit 1.0 of attenuation factors has been removed
since it contradicts to OpenGL specs and does not make sense.
Graphic3d_ZLayerSettings::Lights() - light sources list is now property of ZLayer.
When defined, it overrides light sources defined for View/Viewer.
New class Graphic3d_LightSet has been defined to define a set of light sources.
V3d_Light - removed obsolete interface for debug drawing lights sources.
V3d_Light is now an alias to Graphic3d_CLight.
V3d_TypeOfLight is now defined as a typedef to Graphic3d_TypeOfLightSource.
OpenGl_ShaderManager now overrides THE_MAX_LIGHTS within built-in shading programs
so that maximum number of lights is now limited only by OpenGL hardware
(e.g. length of GLSL program, number of defined uniforms, result performance, etc.).
THE_MAX_CLIP_PLANES is now also defined by OpenGl_ShaderManager,
so that unused lights and clipping planes do not reserve extra uniforms in GLSL programs.
V3d_View::SetLightOn() does not throw exception anymore, when the number of lights exceeds 8.
Instead, OpenGl_ShaderManager::PushLightSourceState() emits warning
in case of usage of FFP providing consistent behavior with Clipping Planes number limit.
OpenGl_LayerList::Render() now handles new option Graphic3d_RenderingParams::ToEnableDepthPrepass
which prepends additional pass to rendering pipeline filling Depth Buffer in advance.
Graphic3d_ZLayerSettings::CullingDistance() and ::CullingSize() - added
new properties configuring culling of small and distant objects, disabled by default.
OpenGl_BVHTreeSelector now handles size culling and distance culling in addition to frustom culling.

vshader Draw Harness command has been extended to support definition
of Shader Object types other than Vertex and Fragment shader.
AIS_Manipulator::ObjectTransformation() - fixed using of manipulator axes
with temporarily applied transformation (when BehaviorOnTransform::FollowRotation is TRUE).
Start axes orientation (at the beginning of Rotation) is now used instead.
