Update empty method guards to new style with regex (see PR).
Used clang-format 18.1.8.
New actions to validate code formatting is added.
Update .clang-format with disabling of include sorting.
It is temporary changes, then include will be sorted.
Apply formatting for /src and /tools folder.
The files with .hxx,.cxx,.lxx,.h,.pxx,.hpp,*.cpp extensions.
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).
