A few texture formats (such as AMD/ATI's ATC texture format, or PVRTC2) were not documented sufficiently by the originator of the format. In these cases, we relied on open source code references from other authors, or information in published articles/papers to implement support for those texture formats in our transcoder. These references are included here.
-ASTC usage follows ARM's [END USER LICENCE AGREEMENT FOR THE MALI ASTC SPECIFICATION AND SOFTWARE CODEC license agreement](https://github.com/ARM-software/astc-encoder/blob/master/LICENSE.md). Note the ASTC texture format is the only standard we could identify that is covered by an explicit end user license, and we believe our use case is covered by this license.
