Yes & no. The snap I'm working on would be a neat demo on two ARM boards
that happen to use different GPUs (the RPi is one of them). Maybe we can
add complexity to the workaround and ship two different GLES libraries, and
select the right one somehow, but perhaps it would be better to wait (kgunn
- if you already have all that tech, a pointer would be appreciated!)

When should we expect support for these API that need a user-side lib (if
I've captured the requirement correctly) from the kernel snap in Snappy?
(perhaps not a question you can answer?)
