[PATCH wayland-protocols, weston 0/10] format modifier support for linux-dmabuf

[Varad Gautam]

Hi Daniel,

Since the v2 appears to be botched up in patchwork, I've put a rebase
onto current master at [1][2]. Do you think we can merge the series yet?

The patches are on top of the roundtrip elimination bits at [3].

Thanks,
Varad
