93cdaa76da 0031196: Visualization, TKOpenGl - enable Ray-Tracing using OpenGL ES 3.2
OpenGl_Context now activates Ray-Tracing and arbTboRGB32 for GLES 3.2.
Removed initialization of some uniforms from GLSL code.
Fixed implicit casts within Ray-Tracing shaders.

ba00aab7a0 0029528: Visualization, TKOpenGl - allow defining sRGB textures
OpenGL rendering is now done into sRGB framebuffer.
OpenGl_ShaderManager::prepareStdProgramFboBlit() has been extended
by programs resolving MSAA texture and applying gamma correction as fallbacks.

Quantity_Color definition has been modified to store RGB components
in linear color space within Quantity_TOC_RGB type.
Standard colors defined by Quantity_NameOfColor enumeration has been updated accordingly.
New Quantity_TOC_sRGB type has been introduced to handle RGB components in non-linear sRGB color space.

OpenGl_TextureFormat class definition has been moved to dedicated files.
New method OpenGl_TextureFormat::FindFormat() replaces OpenGl_Texture::GetDataFormat().
New method OpenGl_TextureFormat::FindSizedFormat() replaces OpenGl_FrameBuffer::getColorDataFormat()
and OpenGl_FrameBuffer::getDepthDataFormat().

Graphic3d_TextureRoot::IsColorMap() - introduced new property defining
if RGB(A)8 image formats should be loaded as sRGB(A) textures or as data RGB(A) textures.
OpenGl_Texture initialization methods have been extended with new theIsColorMap argument.

vreadpixel - added argument -sRGB printing color in sRGB color space.

Test cases have been updated to new sRGB rendered results.

e084dbbc20 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.
vactivate command has been extended with -noUpdate argument.

66d1cdc65d 0030483: Visualization, Path Tracing - make Tile Size configurable
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.

ee5befae97 0027258: Configuration - generate built-in replacement for mandatory resource files
Generation of header files from resource files was added to CMake and genproj procedures.

Message_MsgFile has been extended with new method ::LoadFromString()
for loading messages from embedded resources.
Message_MsgFile::LoadFromString() is now a preferred way
for loading message resources by application
as alternative to environment variables.

TObje/TObj.msg is now embedded into TObj_Application.cxx.
TObj_Application now loads its global messages
on instantiation of the first class instance.

UnitsAPI/Lexi_Expr.dat now completely embedded into Units_Lexicon.cxx.
UnitsAPI/Units.dat now embedded into Units_UnitsDictionary.cxx
but can be regenerated from resource file.
The definition of the following units have been removed:
benne à charbon, calorie (diététique).

Unused message files XSMessage/IGES.us and IGES.fr have been removed.
Related code IGESData.cxx has been removed as well.

XSMessage/XSTEP.us is now embedded into Interface_StaticStandards.cxx
and used for fallback initialization in case when file resources
defined by CSF_XSMessage environment variable are missing.

SHMessage/SHAPE.us is now embedded into ShapeExtend.cxx
and used for fallback initialization in case when file resources
defined by CSF_XHMessage environment variable are missing.
Duplicating code has been removed from ShapeProcess_OperLibrary.cxx.

Shaders/Declarations.glsl and Shaders/DeclarationsImpl.glsl
are now embedded into OpenGl_ShaderProgram.cxx.
CSF_ShadersDirectory is no more required for using OCCT 3D Viewer.

Ray-Tracing GLSL programs from Shaders are now embedded into OpenGl_View_Raytrace.cxx.
File resources are still used instead of embedded programs
when CSF_ShadersDirectory is defined, but this functionality
is intended for OCCT development.

Enumeration Graphic3d_ShaderProgram::ShaderName_Phong
demonstrating custom GLSL program usage has been removed.
