This package contains UVAtlas, a shared source library for creating and packing an
isochart texture atlas.

The source is written for Visual Studio 2013 or 2015. It is recommended that you
make use of VS 2013 Update 5 or VS 2015 Update 3 and Windows 7 Service Pack 1 or later.

These components are designed to work without requiring any content from the DirectX SDK. For details,
see "Where is the DirectX SDK?" <http://msdn.microsoft.com/en-us/library/ee663275.aspx>.
