I have not yet had a chance to look at the patch because I was busy with many
things last week. I've put on my calendar to review your patch tomorrow
(Tuesday) morning from 10am-11am. Apologies for not responding sooner.

If possible, I would like Waffle to build against ICS and Jelly Bean. Perhaps
we can accomplish that with a CMake option, such as
- -Dwaffle_android_version={ics,jb}, and an #ifdef. However, let's get your
patch in first and make this change afterwards.

Piglit users, at least those testing Piglit on Windows and Xorg, like to have
keyboard and mouse input for some tests. Personally, I disklike this
requirement, but if Waffle is to completely replace Glut then the input
requirement must be satisfied on those two platforms.

However, there is no precedent for Piglit on Android. If you feel that
implementing input will be difficult and error-prone, then I suggest that, at
least tentatively, Waffle should not support input on Android. The
waffle_X_get_native functions should return NULL and emit
WAFFLE_ERROR_UNSUPPORTED_ON_PLATFORM.
