Description:
This directory contains an ETC1 encoding API.  The source derives from
frameworks/base/opengl/include/ETC1/etc1.cpp from the Android Open Source
Project.

Local modifications:
- Removed decoding.
- Generalize so that output size is independent of input size.
- Handle cases of out-of-bounds blocks along the image boundary.
