Subject: Unity8 performance boost, almost there

All,

It's been a while coming, but the pieces are almost all in place for 
what could be a significant performance boost to Unity 8.

It started with basic occlusion detection in Mir:
https://bugs.launchpad.net/mir/+bug/1227739

And then recently progressed with opaque pixel format support:
https://bugs.launchpad.net/mir/+bug/1240833

So now the only piece missing is a fix for platform-api, to choose a 
non-alpha pixel format by fixing:

static MirPixelFormat
mir_choose_default_pixel_format(MirConnection *connection)
{
     MirDisplayInfo info;
     mir_connection_get_display_info(connection, &info);
     return info.supported_pixel_format[0];
}

(https://bugs.launchpad.net/mir/+bug/1227739)

When all put together with Mir 0.1.2+, I hope you will find the Unity8 
touch experience to be noticeably smoother.

- Daniel

Just waiting for Mir 0.1.2 to hit the archive (now done), _and_ for 
someone to fix platform-api 
(https://bugs.launchpad.net/mir/+bug/1227739). That could be me, or 
anyone else...

ricmm will be off for the rest of the week, so feel to propose a mr
for the platform-api branch (I can review & test if needed, just ping
me on irc).
