Render: Improved vertex color support (@zpl-zak)
Render: Fixed wrong axis order used during model import (BREAKING!) (@zpl-zak)
Render: Revamped the model API (BREAKING!) (@zpl-zak)
Render: Added fog support (WIP!) (@zpl-zak)
Render: Revamped the shader system to be more flexible and modular (@zpl-zak)
