[FFe] Add support for OpenGL|ES

[Daniel van Vugt]

== Feature ==
Rework compiz plugins to support OpenGL|ES, which is a limited subset of regular OpenGL. This is required so that we can support ARM platforms from the main source tree in future, without patches.

== Issues causing the need for exception ==
It wasn't completed on time to make feature freeze. Although, realistically, it was completed earlier than we expected just recently.

Hey,

Can you provide some more details of the testing you've done on this branch? Is there any chance of regressions on non-gles arches from this work or is it isolated? How much further work do you imagine is required before this is considered complete?

Cheers.

I'm not sure if Daniel is still around today and that really needs to land if we want an armel desktop in beta1...

Some infos:

- this version was tested through the developpement by the compiz team (Daniel and Sam mostly) on various hardware

- issues found were collected on https://bugs.launchpad.net/compiz/+bugs?field.tag=gles and https://bugs.launchpad.net/unity/+bugs?field.tag=gles

not that those bugs don't all concern the default installation, quite some track things missing in optional compiz options

- the version is being tested with the new unity in a ppa for some day by different people, a few bugs were found but no stopper so far

- the version was tested on armel and it was confirmed it makes unity-3d run again there

oh, GLES is only enabled on arm* but there are chances to the compiz codepath for the non GLES cases as well so it's not a no-op for compiz on other architectures either...

[Iain Lane (laney)]

OK, approved. Please could somebody make sure that the important bugs are tracked and milestoned for the distro (add distro task and milestone for b2).

Thanks Iain
