0030182: Visualization, Image_AlienPixMap - support reading encoded image from memory buffer

Added two new Image_AlienPixMap::Load() methods, taking std::istream
and memory buffer (pointer, length) arguments.
This allows reading image from application memory or from file with non-zero offset.

Added Image_AlienPixMap::IsTopDownDefault() static property allowing to query rows order used by linked image library,
so that application might generate UV texture coordinates accordingly.

Added missing Release() to IWICImagingFactory instance.

0024437: Visualization - silhouette edges based on OpenGL

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.

0029076: Visualization - implement element shrinking Shader

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

When DRAW on Windows is launched with option -c, the command is now properly transferred to Tcl thread (separate thread that runs Tcl interpretor on Windows except when DRAW is run in batch mode) for execution, instead of being evaluated in the main thread.

Execution of DRAW in batch mode (option -b) is fixed by enabling proper initialization of the Tcl interpretor and replacement of backslashes in path to startup script by straight slashes on Windows in that mode.

Declaration of global variables used for communication of console command between threads is moved to Draw_Window.hxx to ensure consistency.
Function wscpy_s is used instead of memcpy to avoid possible buffer overrun.

0029683: Add functionality to make the TopoDS_Shape periodic in 3D space

Implementation of the new class *BOPAlgo_MakePeriodic* for making the shape periodic in 3D space.
Periodicity of the shape means that the shape can be repeated in any periodic direction any number of times without creation of the new geometry or splits.
The idea of this algorithm is to make the shape look similarly on the opposite sides or on the period bounds of periodic directions.
It does not mean that the opposite sides of the shape will be mirrored. It just means the the opposite sides of the shape should be split by each other and obtain the same geometry on opposite sides.
Such approach will allow repeating the shape, i.e. translating the copy of a shape on the period, without creation of new geometry because there will be no coinciding parts of different dimension.

Draw commands for the new algorithm:
* makeperiodic - makes the shape periodic in required directions;
* repeatshape - repeats the periodic shape in requested periodic direction;
* periodictwins - returns the periodic twins for the shape;
* clearrepetitions - clears all previous repetitions of the periodic shape.

0027620: Test perf bop boxholes crashes DRAW

Implementation of capturing of output to standard streams in DRAW (see command dlog) is revised to avoid problems with command "test" executing long test scripts:

1. Method OSD_File::Capture() is removed: on Windows it was allocating a C file descriptor for a file opened using WinAPI, and never released that descriptor (once allocated, it cannot be released separately from WinAPI file handle). Direct calls to dup/dup2 are used instead.

2. In Draw_Window.cxx the standard Tcl channels are initialized manually using corrected version of Tcl internal function. This works around a problem with Tcl channels on Windows being bound to OS device handle owned by the system which can get invalidated as result of calls to dup2() (used to capture output to standard streams).

3. Temporary file for capturing is opened once and used to store whole log, thus the need to collect log in the string stream in memory is avoided

4. Possible errors of dup() and dup2() are checked and reported

Test demo draw dlog is added

Off-topic changes:

- Test demo draw getsource is corrected for VS2017 which generates file name in lowercase
