What is the maximum texture size etcpack can handle?

Thanks for the replies!

I was doing some tests with a large texture atlas. The atlas actually ended up being 16k x 8k when etcpack ran out of memory. For testing purposes I put together a 64-bit compression tool, taking advantage of one of the ETC open source implementations out there. Even though I had to implement support for ETC2 with alpha, it was a quick enough exercise. My test may not be a valid use case for most devices but I didn't see any documented maximum texture size for etcpack so even if etcpack won't see an updated to support large textures then it may be good to document the maximum texture size it can handle.
