- Refactored DirectRendering class to support new IDirectRendering interface and manage textures directly. - Enhanced ImmediateMode to utilize ImmediateVertex struct for immediate rendering calls. - Updated Image class to use IDirectRendering for texture creation. - Modified test application to demonstrate immediate mode rendering with new structures. - Removed obsolete code related to previous rendering abstractions.
