UVAtlas - isochart texture atlasing
-----------------------------------
Copyright (c) Microsoft Corporation. All rights reserved.
February 8, 2019
This package contains UVAtlas, a shared source library for creating and packing an
isochart texture atlas.
This code is designed to build with Visual Studio 2015 Update 3 or Visual Studio 2017.
It is recommended that you make use of VS 2015 Update 3, Windows Tools 1.4.1, and the
Windows 10 Anniversary Update SDK (14393) -or- VS 2017 (15.9 update) with the
Windows 10 October 2018 Update SDK (17763).
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>.

RELEASE NOTES
-------------
* The VS 2017 projects make use of /permissive- for improved C++ standard conformance. Use of a Windows 10 SDK prior to
the Fall Creators Update (16299) or an Xbox One XDK prior to June 2017 QFE 4 may result in failures due to problems
with the system headers. You can work around these by disabling this switch in the project files which is found
in the <ConformanceMode> elements.
* The VS 2017 projects require the 15.5 update or later. For UWP and Win32 classic desktop projects with the 15.5 -
15.7 updates, you need to install the standalone Windows 10 SDK (17763) which is otherwise included in the 15.8.6 or
later update. Older VS 2017 updates will fail to load the projects due to use of the <ConformanceMode> element.
If using the 15.5 or 15.6 updates, you will see "warning D9002: ignoring unknown option '/Zc:__cplusplus'" because
this switch isn't supported until 15.7. It is safe to ignore this warning, or you can edit the project files
<AdditionalOptions> elements.
* The UWP projects include configurations for the ARM64 platform. These require VS 2017 (15.9 update) to build.
