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).

RayTracingTileSize for testing various tile configurations.
Default behavior is the following:
- Target number of tiles (e.g. upper limit per frame): 256
- Tile size: 32x32.
OpenGl_View::runPathtrace() has been split into two methods per rendering stage.
OpenGl_Texture::Init() now returns FALSE immediately on 0 input dimensions.
Added Image_PixMapTypedData template class allowing to work with image data of known pixel format.

(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).

In command vreadpixel OpenGl-related warnings are redirected to cout so that they do not contaminate the command output.
Test grid caf presentation is configured to ignore OpenGl-related warning messages.
Tests in grid tools are configured to report status SKIPPED if tools are not available (OCCT is built without Qt).
Eliminated usage of TEXT macros, usage of OSVERSIONINFO instead of OSVERSIONINFOW.
LoadIcon/LoadCursor are now used instead of LoadIconW/LoadCursorW
when passing macros to standard resources (which depend on UNICODE flag).

Quantity_PlaneAngle, Quantity_Length, V3d_Parameter and V3d_Coordinate
have been replaced by Standard_Real in visualization classes.
Weighted, Blended Order-Independent Transparency algorithm has been added rasterization pipeline.
In contrast to classical blending transparency it makes transparent objects look independent
from point of view. It also gives better depth occlusion when being used together with a weight factor
based on value of a GL depth buffer. The feature supports desktop OpenGL, OpenGL ES 3.0, ANGLE
and can be used together with MSAA on desktop GL.
To be used it require availability of:
1) Shaders pipeline.
2) Floating point color format for framebuffer (GL_ARB_color_buffer_float).
3) Multiple render targets (GL_ARB_draw_buffers).
Patch does not modify API and does not require application porting.
It adds new rendering options to Graphic3d_RenderingParams structure:
a) Transparency method from enumeration.
b) Scalar factor [0-1] controlling influence of a fragment's depth to its visibility.
Patch also simplifies processing of transparent objects for standard method:
rendering priority of transparent graphical structures is managed automatically,
therefore there is no need to care about it at application's side.
