faff37677c 0031478: Visualization, TKOpenGl - allow uploading Cubemap in compressed DDS format when supported by GPU
Graphic3d_TextureRoot::GetCompressedImage() - added new interface for fetching compressed texture image.
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).

fc552d842e 0030692: Data Exchange - introduce base framework RWMesh for importing mesh data formats into XDE document
RWMesh_CafReader - added new interface class for common workflow for reading mesh data files into XDE document.

OSD_Path - added auxiliary methods splitting path into folder+file pair
and checking relative/absolute path semantically:
OSD_Path::FolderAndFileFromPath(), ::IsRelativePath(), ::IsAbsolutePath().

V3d_TypeOfOrientation enumeration has been extended with aliases
(like front/left) for Z-up and Y-up conventions.
V3d_View::SetProj() now accepts argument for asking Y-up instead of Z-up.

Added command vviewproj defining standard camera direction.
Commands vaxo, vleft, vright, vtop, vbottom, vfront, vbottom now redirect to vviewproj.

TCollection_AsciiString::SubString() now uses Standard_OutOfRange_Always_Raise_if() to suppress GCC warning.

Eliminated gcc 4.4 compilation errors within Standard_OutOfRange_Raise_if,Standard_RangeError_Raise_if.

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.

08f8a1854d 0025382: Visualization, TKOpenGl - improved video recording capability
Image_VideoRecorder - added new class for video recording using FFmpeg framework.
Draw Harness command vanimation has been extended with new options for video recording.
New optional dependency has been introduced - CSF_FFmpeg.

dc858f4c5a 0028441: Coding Rules - move out nested Image_PixMap::ImgFormat enumeration to dedicated enum Image_Format
Enumeration Image_PixMap::ImgFormat, previously declared as nested
enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.

The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.

a13f2dc486 0027566: Configuration - define Handle_ as non-template class for compatibility with C++/CLI
For MSVC compiler (version 12 and above), Handle_Class types are defined as true classes (inheriting corresponding opencascade::handle<Class>) to allow using them in "public" statement of C++/CLI language, to make these classes recognizable by other C++/CLI libraries.

Code to test operations with Handle_ class is added to QAHandleOps test command

19286d7cf7 0025114: CMake-based build tools for OCCT 7.0
All CMake meta-projects for OCCT are put to OCCT code (including fragments previously generated by WOK).

"/bigobj" compiler flag added to TKQADraw because of the size of its object file

[GeomToStep & Graphic3d] private headers are included from current dir of including source file

42cf5bc1ca 0024002: Overall code and build procedure refactoring -- automatic
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack

bf75be9867 0023544: Texture management in TKOpenGl should be redesigned
Structures Graphic3d_CView, Graphic3d_CStructure, Graphic3d_CGroup become classes and their definitions moved from InterfaceGraphic to Graphic3d.
Introduced new class OpenGl_Texture as replacement for OpenGl_ResourceTexture class and static functions in OpenGl_TextureBox.
Graphic3d_TextureRoot now no more communicate within Graphic3d_GraphicalDriver.
Instead class returns image through GetImage() method.
OpenGl_AspectFace - avoid possible NULL-dereference
OpenGl_Texture::Init() - check gluBuild2DMipmaps() return value
OpenGl_Texture - check GL_BGRA_EXT for compatibility
OpenGl_Texture - scale NPOT image when required
Added more description to Graphic3d_TextureRoot class
OpenGl_Texture - added missing break statement for ImgBGR32 case
OpenGl_Workspace::setTextureParams() - fixed local variable aFilterMin overrides visibility of early declared variable
OpenGl_Workspace::DisableTexture() - reset texture matrix
FTGL do not reset texture matrix and corrupt text could be rendered if custom texture has not identity texture matrix.

692613e554 0023272: Image comparison algorithm
A new class Image_Diff for comparison of images
and a draw-command "diffimage", which compares 2 images.

Image_PixMap redesigned to provide interface for low-level image operations.
New Image_AlienPixMap class now intended for Save/Load functionality.

Aspect_PixMap class dropped.
Xw_PixMap and WNT_PixMap classes now do not inherit from Aspect_PixMap and deprecated.

ToPixMap methods now retrieve Image_PixMap as argument.

Conflicts:
src/ViewerTest/ViewerTest.cxx
Remarks applied
Fix compilation (correct merging error)

Eliminated Aspect <-> Image cyclic dependency

Fixed GIF dump in case of BGR32 image format
