Methods ParseOnOff()/ParseColor() have been moved from package ViewerTest to Draw.
Command "vlight -color" now accepts RGB values, not only name.
Implementation of pload command has been cleaned up.

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).
V3d_View::AutoZFit() is now called only before redraw
within methods V3d_View::Redraw() and V3d_View::Update().

in addition to active camera matrices.
genproj.tcl has been extended to handle optional CSF_OpenVR dependency.
Added short-cuts methods in Message_Messenger for sending message with specified gravity,
and stream buffer class for using stream-like interface for that.
Similar short-cuts to DefaultMessenger() are added in Message package.
ViewerTest has been updated to send messages to Message::DefaultMessenger()
instead of direct output to std::cout/std::cerr.
Off-topic: spelling error (duplicate "and") is corrected in two places
Added test bugs fclasses bug31189
A special mode for the selecting by polygon is added to select only completely overlapping objects.
In order to track the sensitives that were included completely by defined polygon, the boundary points of the polygonal frustrum are stored in the variable myBoundaryPoints.
If an sensitive intersects with at least one of the frustrums from myFrustums, then checking whether this object intersects with borders using the isIntersectBoundary method; if not, then the sensitive were included completely by defined polygon.
Because the polygon can be concave, then to check the sensitive were included completely by defined polygon, it is not enough to check of all its points, it is necessary that the edges of the sensitive do not intersect polygonal frustrum. To do this, for polygonal selection, a call to the Overlaps method for a point was replaced by a call to a segment where necessary.
bugs/vis/bug31440: test case added
OpenGl_Element now provide methods ::UpdateMemStats() and ::UpdateDrawStats()
for unified request of statistics used by OpenGl_FrameStats instead of direct handling of OpenGl_PrimitiveArray.

to match Prs3d_Drawer::HLRAngle() which has been previously used in majority of cases.
Removed unused property HLRBRep_PolyAlgo::Angle().

- Tool genconf recognizes availability of ClangCL toolset and proposes it in the list
- Tool genproj recognizes new compiler specification VCVER=vclang and generates VS 2019 projects for it
Note that vclang configuration puts binaries to folder "vc14" as it is compatible with vc14 CRT.

- In .lex files, pragmas are added to disable warnings in parser code
- In OSD, signature of function _osd_wnt_set_error() is corrected to avoid warning on incorrect use of va_args (undefined behavior)
- In OSD_Host, OSD_Parallel_TBB, warnings on usage of deprecated function are disabled

Test case for this bug has been added.
Aspect_Window::InvalidateContent() - added new virtual method for invalidating window content using platform-specific API.
TKDraw, tkLoop() on Window platform has been changed so that to prevent
continuous input window events blocking terminal input
(e.g. in case if processing events is not fast enough or
if another continuously sends new events).
TKViewerTest, on X11 platform has been fixed a message processing
so that to avoid messages being not processed.
Added aggregation of Exposer and ConfigureNotify events.
Fixed aggregation MotionNotify events.
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.
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).

Although atomic operations on floats allows single-pass rendering,
such operations leads to instability in case of different calculation order.
Atomic float operations are also currently supported only by single GPU vendor.
Fixed GLSL compilation on Intel drivers (follow ARB_shader_image_load_store
specs rather than EXT_shader_image_load_store).

and can be switched into Graphic3d_RenderingParams::FrustumCulling_NoUpdate state
useful for debugging the algorithm.
