Patchwork [01/16] qt4-graphics-system: add

Allow setting default runtime graphics system engine for Qt4
applications per machine.

Depending on the GPU and Xorg driver, this can boost and impact
significantly the drawing performance. The default setting is to
'raster' as this offer best performance for most machines GPUs.

We don't have an xserver-common in oe-core, what does it provide?

Is this something that we need to merge over?

Sau!

that's x11-common equivalent in meta-oe, VIRTUAL_RUNTIME should be used
here like in meta/recipes-sato/tasks/task-core-x11.bb

# xserver-common, x11-common
VIRTUAL-RUNTIME_xserver_common ?= "x11-common"

xserver-common added functionality (like xinput-calibrator) should be merged 
to x11-common and then xserver-common dropped from meta-oe, but I'm
still busy with other stuff and daywork..

Cheers,

Done locally; will send an update patchset with this.

It would be awesome if you could look on that soon; this would reduce
another set of delta between OE-Core and Meta-OE.
