The files with .hxx,.cxx,.lxx,.h,.pxx,.hpp,*.cpp extensions.

Wrappers of system OpenGL 1.1 / OpenGL ES 2.0 functions have been moved to OpenGl_GlFunctions.cxx.
Avoided usage of global OpenGL functions in OpenGl package outside of OpenGl_GlFunctions.cxx.
OpenGl_FrameBuffer::Init() now creates MSAA render buffer in case if MSAA textures are unsupported.
In this case OpenGl_View::prepareFrameBuffers() creates MSAA render buffer for main content
and non-MSAA FBO for immediate content as blitting of MSAA render buffers into MSAA targets is unsupported by OpenGL ES 3.0.
env.bat.in has been corrected to include path to custom ANGLE (GLES2_DIR)
in front of Qt which might include its own older ANGLE build.
GL_HALF_FLOAT_OES from OpenGL ES 2.0 extension
is now avoided within OpenGL ES 3.0+ context in favor of GL_HALF_FLOAT.
emscripten_webgl_enable_extension() is now called for all extensions
checked by OpenGl_Context::CheckExtension().

Xw_Window.hxx now export class on non-Linux platforms.
OpenGl_Window now creates an off-screen EGL surface also in case of

OpenGl_GlCoreXX function tables no more defined two hierarchies with and without FFP functions,
and OpenGl_Context::coreXXback fields have been removed.
Introduced OpenGl_Context::core11ffp as more straightforward naming for obsolete FFP function set.
Graphic3d_ShaderManager::stdComputeLighting() - implementation has been adjusted
for better consistency between PBR / non-PBR.
OpenGl_Material definition has been modified to join Front/Back pair into a single uniform variable.
Common material definition now occupies 4x2 vec4 instead of 5x2 vec4.
Getters of Common material properties within Declarations.glsl
have been renamed to match PBR material syntax (e.g. take IsFront flag as function argument).
Auxliary macros (like occTextureColor()) has been renamed (like occMaterialBaseColor())
and adjusted to return material property directly instead of taking it as argument.
Added new property Graphic3d_Camera::IsZeroToOneDepth() and OpenGl_Caps::useZeroToOneDepth
for activating [0,1] depth range instead of [-1,1] range using glClipControl() within OpenGL 4.5+.
OpenGl_Workspace::Activate() now implicitly disables OpenGl_Caps::ffpEnable when it is unsupported.
OpenGl_AspectsSprite::build() now ignores OpenGl_Caps::pntSpritesDisable when Display Lists are unsupported.

Removed initialization of some uniforms from GLSL code.
Fixed implicit casts within Ray-Tracing shaders.
Added image formats Image_Format_RGF_half/Image_Format_RGBAF_half
with manual conversion between 32-bit float and 16-bit half-float values.
PBR LUT table is now converted into GL_HALF_FLOAT_OES data format in case of OpenGL ES 2.0.
Added OpenGl_Context::hasUnpackRowLength property for using GL_UNPACK_ROW_LENGTH in runtime.
OpenGl_Texture now uses GL_UNPACK_ROW_LENGTH on OpenGL ES 3.0 when necessary.
OpenGl_Texture::InitCubeMap() now allows uploading vertically-stacked cubemaps
without GL_UNPACK_ROW_LENGTH requirement.
Added "#define occLight_Index(theId) 0" workaround allowing to compile
a single light source PBR shading program on OpenGL ES 2.0,
as it disallows non-constant index expressions (even trivially deducable at compile-time).
PBR lookup table is now automatically resized to RGBA format
when RG texture format is unsupported (OpenGL ES 2.0).
OpenGl_ShaderManager now allows compiling PBR shaders
using WebGL 1.0 + GL_EXT_shader_texture_lod extension.
PBR IBL baking GLSL program has been redisigned to use
if/else to avoid non-constant index expressions.
Diffuse baking implements packing float values into a temporary RGBA8 texture
as a fallback solution on WebGL 1.0 implementations supporting float textures
but not as FBO render targets.
OpenGl_PBREnvironment now uses GL_FRAMEBUFFER instead of GL_DRAW_FRAMEBUFFER
for compatibility with OpenGL ES 2.0.
Error messages in TKOpenGl package have been improved to format
GLenum values as string constants or hex values.
OpenGl_VertexBuffer::init() now logs a message with error details
instead of just returning Boolean flag.
Graphic3d_RenderTransparentMethod has been extended by Graphic3d_RTM_DEPTH_PEELING_OIT,
which is handled by OpenGl_LayerList::renderTransparent().
OpenGl_FrameBuffer::Init() now does not silently ignore unknown color attachment format and return failure.
OpenGl_FrameBuffer::InitWrapper() - added constructor wrapping existing color textures.
v3d/transparency/oit: test case added
Graphic3d_CLight::ToCastShadows() - added new property defining if light should cast shadows (ignored by Ray-Tracing).
OpenGl_ShaderManager::stdComputeLighting() now implements shadow mapping for directional lights.
OpenGl_ShaderManager::prepareGeomMainSrc() now handles copying of arrays.

vrenderparams - added new parameters -shadowMapResolution and -shadowMapBias.
Added OpenGl_Caps::buffersOpaqueAlpha option allowing to disable writes
into alpha component of color buffer and keep it opaque.
Added OpenGl_Context::SetColorMaskRGBA() method overriding each color component deliberately.
New option is set within WebGL sample.
OpenGl_Context now skips loading functions related to mapping buffer,
which are required by OpenGL ES 3.0 specs but not provided by WebGL 2.0.
Message_PrinterSystemLog does not use a broken emscripten_log() anymore, which corrupted UNICODE strings.
WasmOcctView::initWindow() - callbacks now set using EMSCRIPTEN_EVENT_TARGET_WINDOW
instead of 0 used by older Emscripten API.
Mouse callbacks now track canvas element and use
EmscriptenMouseEvent::targetX/targetY instead of ::canvasX/canvasY
as the latter was broken.
Added emscripten_set_main_loop() setup to shut up eglSwapInterval() error message.
Fixed missing \0 at the end of string converted by toUtf8Array().
Added OpenGl_Context::GetBufferSubData() implementing getBufferSubData() based on capabilities of various APIs.
Added OpenGl_VertexBuffer::GetSubData() similar to OpenGl_VertexBuffer::SubData().
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).
Fixed -Wrestrict warning within OSD::SetSignal().
Fixed -Wdeprecated-copy warning by adding missing counterpart
in pair copy constructor / assignment operator or by removing trivial constructor.
AdvApp2Var_Node, AdvApp2Var_Patch are now declared as Handle.
AdvApp2Var_Iso is now passed by Handle.
Disabled operator= for TDF_Transaction and TDF_IDFilter.
Standard.cxx - fixed GCC version mischeck causing building failure with experimental GCC versions.
TopOpeBRepDS_EXPORT.cxx - fixed -Wmaybe-uninitialized warnings.
V3d_View::AutoZFit() is now called only before redraw
within methods V3d_View::Redraw() and V3d_View::Update().
Graphic3d_CView now holds Aspect_ExtendedRealitySession object.
Aspect_OpenVRSession implements new interface via optional OpenVR library.
Graphic3d_CView::ProcessInput() - added new interface method
which should be called for processing positional input (head tracking).
Graphic3d_Camera now allows setting custom stereoscopic Projection matrices.
OpenGl_Context::Camera() - context now holds Camera object
in addition to active camera matrices.
genproj.tcl has been extended to handle optional CSF_OpenVR dependency.
