2D normal map creation tool

This projects was part of my graduation work. The goal was to create an application using C# that allows for dynamic lighting of 2D objects in a game. It was written as a separate library (DLL) and incorporated in a Unity tool.
The tool got slightly out of hand and included features out of the scope of the project but nonethless usefull for asset creation in Unity.
The available tools include the normal generator, a painting tool and a sprite-sheet editing tool.
