- New class SelectMgr_BVHThreadPool manages background processing of BVH building queue.
- Added Select3D_SensitiveEntity::ToBuildBVH() method that checks if BVH (if it used) is in invalidated state. Defined this method for all standard classes inherited from Select3D_SensitiveEntity.
Added missing NULL checks before accessing GetInteractor().
Errors are now reported using Message::SendFail().

Triangle orthogonal to view direction is now handled as a segment.
myViewRayDir field is now defined as normalized vector to avoid confusing math.
For the case when the segment and myViewRayDir are almost parallel,

be the correct value, therefore it is better to pass a segment that will not
be parallel to myViewRayDir as an argument to the function.
vpoint command has been extended by arguments -2d and -nosel
for displaying picking mouse position as on-screen point in pixels.
Fixed double-binding-map error in case of displaying point with already used name.

Graphic3d_TextureRoot::GetCompressedImage() - added new interface for fetching compressed texture image.
Default implementation detects DDS image files using Image_DDSParser parser.
Graphic3d_TextureRoot::GetImage() has been extended with new parameter
- the list of image formats supported by OpenGL driver.
Graphic3d_TextureRoot::convertToCompatible() implicitly converts
BGRA image to RGBA on OpenGL ES, which normally does not support BGR formats.
OpenGl_Caps::isTopDownTextureUV - new property defines how application defines
UV texture coordinates in primitive arrays.
OpenGl_Context::SetTextureMatrix() compares this flag with OpenGl_Texture::IsTopDown()
and automatically flips V coordinate in case of mismatch.
OpenGl_Texture now holds exact number of mipmap levels
instead of Boolean flag indicating that they are defined.
This allows loading DDS files with incomplete mipmap level set
by setting GL_TEXTURE_MAX_LEVEL to appropriate value instead of default 1000
(causing black textures in case if mipmap levels are not defined till 1x1).
Fixed order of texture coordinates transformation within GLSL program to match FFP matrix:
Rotate -> Translate -> Scale (previously Rotation was applied afterwards).

PBR shading model requires OpenGL 3.0+ or OpenGL ES 3.0+ hardware.
Environment cubemap is expected to be provided for realistic look of metallic materials.
occLight_IsHeadlight() now returns bool instead of int.
Avoid using lowp for enumerations to workaround occLight_IsHeadlight()

vstate - added NULL checks.
vdisplay now prints error on attempt to specify unsupported display mode.
verase, vremove now raise Tcl exception on attempt to hide non-existing object.
verase, vremove, vdir now accept name masks like "verase b*".
vremove and vdir output is now consistent to verase command (space-separated list of removed objects).
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.
OpenGl_AspectsTextureSet now appends Sprite texture to the end of texture set.
OpenGl_Context::init() - fixed usage of GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS on too old GL context.
Default sampler names occSampler0, occActiveSampler and occSamplerBaseColor

OpenGl_ShaderObject::LoadAndCompile() and OpenGl_ShaderProgram::Link()
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).
Added hints about ZLayer consideration and changing highlight colors to documentation
of AIS_InteractiveContext::SetHighlightStyle() method.

and performs full Redraw() instead of RedrawImmediate().
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.
