* Sync with bgfx upstream revision b91d0b6 * Sync with bx upstream revision d60912b * Sync with bimg upstream revision bd81f60 * Add astc-codec decoder * Rename VertexDecl to VertexLayout * Rename UniformType enum Int1 to Sampler. * Add NVN stub * Fix unused-const-variable error on macOS * Drop redundant explicit language parameters buildoptions_cpp are only applied to c++ files and buildoptions_objcpp are only applied to objective c++ files. As such, hardcoding -x offers no benefit while preventing overrides (such as one needed by 3rdparty/bgfx/src/renderer_vk.cpp on macOS) from working. * Re-introduce -x c++ in places where C code is compiled as C++ to prevent clang from throwing a warning * Build bgfx as Objective-C++ on macOS It is needed due to included headers * Enable Direct3D12 and Vulkan bgfx rendering backends * Enable building of spirv shaders * Properly escape /c in cmd call * Comment out dx12 bgfx renderer * Honor VERBOSE setting during shaders build * Only invert hlsl shader XYZ_TO_sRGB matrix for opengl * Add spirv shaders * OpenGL ES needs transposed matrix too * Metal needs transposed matrix as well
