v0.2.0

Added

• DirectX 12 backend
• DNN denoising (using weights from OIDN)
• GPU ray sorting
• Better memory allocator for GPU backends
• Physical sky (as baked env texture)
• Pipeline HWRT invocation (Vulkan only, disabled for now)
• Detailed denoising tests, basic samples

Fixed

• Incorrect camera far clipping
• High memory consumption with Vulkan
• Bright pixels burn-in with filmic tonemapping
• Env map seam (GPU only)
• Incorrect directional light caustics
• Crash on weird resolutions (e.g. 513x513)
• Negative color values (GPU only)

Changed

• Texture filtering is done stochastically
• Tests are invoked in parallel
• VNDF sampling is simplified (using spherical caps method)
