Method IGESToBRep_BRepEntity::TransferEdge() is fixed to record result even if it is wire rather than edge.
This allows translation of EdgeLoop entities referring to CompositeCurve items in EdgeList entities.

Method IGESToBRep_BRepEntity::TransferLoop() is improved to skip failed edges thus avoiding exception and allowing translation to complete for transferable entities.

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.

0030497: [REGRESSION] Mesh - wrong Poly_Polygon3D within local selection of located shape

The previous code has a condition to avoid processing the same faces if the face has a location.
The similar condition should be applied during the edges processing.
If not doing this, in the previous implementation, IMeshData_Edge instances are created for all edges(even located), but edges of faces located are not filled with curves.
As a result we had wrong local selection of edges.

Limit addition of edges to data model by ones with unique TShape and location using edges map already available in BRepMesh_ShapeVisitor.

0029810: Visualization - Tool for debugging shaders

A new tool for debugging shaders has been introduced.
The new method OpenGl_ShaderProgram::UpdateDebugDump() allows dynamically
dumping/restoring certain shader program (vertex and fragment shaders) to/from external file.

The file name is generated from the program's name with suffix ".vs" or ".fs" for shader type.
The environment variable CSF_ShadersDirectoryDump specifies the folder for dumps.

If the file does not exist (first frame), then it is automatically saved.
When the file date/time is changed in comparison with recent cached date,
then the file will be automatically loaded from external file,
thus this file can be modified in any editor.

OpenGl_ShaderManager now generates a human-readable resource ids for standard GLSL programs.

Draw Harness command vshader has been extended with arguments -list,-dump and -reload
for debugging shaders within OpenGl_Context.

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.
ViewerTest::ParseColor() now parses RGBA color.

Redundant command BUC60738 has been removed.
AIS_ColorScale - fixed usage of uninitialized FillArea aspects.

0030476: Visualization, Path Tracing - Adaptive Screen Sampling leads to unstable results

OpenGl_View::runPathtrace() has been extended with alternative multi-pass
Adaptive Screen Sampling mode, not relying on atomic floating point operations.
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).

Graphic3d_RenderingParams::AdaptiveScreenSamplingAtomic option has been added
to activate 1-pass Adaptive Screen Sampling mode when supported by hardware.

vfps command has been extended with -duration argument allowing to limit command execution time.

OpenGl_TileSampler has been refactored to better describe its logic:
- Offset image now defines tile index instead of offset to tile origin.
- Added 2D array defining the number of times to sample tile for straight-forward debugging.

Graphic3d_RenderingParams has been extended with property
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.

- Allow mapping multiple fonts to a single alias.
- Log informative message about usage of non-requested font (fallback).
- Register all font files within standard folders on Linux when "fonts.dir" is not found.
- Prefer specific alias ("serif") as default fallback font instead of arbitrary one in a system.

A couple of obsolete and broken font aliases have been removed;
instead, new aliases of fonts popular on Linux platform have been added.

Font_NameOfFont.hxx has been extended with more neutral aliases

0030346: Modeling Algorithms - BRepPrimAPI_MakeRevol throws "BRepSweep_Translation::MakeEmptyVertex"

Implementation of method "IsDeleted(...)" for MakeRevol and MakePrism algorithms.

Problem (exception) occurs during history building and was caused by an attempt to obtain generated shape for subshape, which was really "deleted" by algorithm - this input subshape and its possible generated shape was not used in result.

0030364: Visualization, TKOpenGl - allow initializing a Surface-less EGL context

OpenGl_Context::MakeCurrent()/OpenGl_Context::IsCurrent() have been modified to NOT fail
in case if myWindow is EGL_NO_SURFACE (valid off-screen rendering case within EGL).
OpenGl_GraphicDriver::InitEglContext() now finds EGL surface config in case if it has not been passed by argument.

OpenGl_Window constructor now allows wrapping an off-screen rendering surface EGL_NO_SURFACE.
However, it still creates a dummy surface eglCreatePbufferSurface() to workaround bugs in some GLES drivers (Vivante GC2000).

V3d_View::SetWindow()/V3d_View::MustBeResized()/V3d_Viewer::SetViewOn() have been modified
to avoid implicit View redraw (leading to undefined behavior/crashes in case if rendering
should be done into default FBO defined right after V3d_View initialization).

0030396: Infinite recursion during ShapeFix after BRepAlgoAPI_Cut

Two test cases are added. One for Boolean operation (it is good, because BO has been fixed already), and another for fixshape operation (it causes Draw crash).

1. Test case for the issue has been created.
The problem is still reproduced on MASTER.

2. Some test cases have been moved to lowalgos/2dinter grid.
