- Added D3D12ResourceFactory for creating render targets, textures, and buffers. - Enhanced D3D12SwapChain to manage back buffer render targets and provide access to them. - Updated D3D12Texture to utilize resource handles for better resource management. - Removed legacy ResourceAllocator and integrated improvements for resource handling. - Introduced new interfaces for resource factory and swap chain to streamline resource creation. - Added support for mip levels and texture dimensions in render target and texture descriptions. - Created new markdown files to document allocator and swap chain improvements.
