[PATCH weston 0/4] RFC: Output layout configuration

[Armin Krezović]

This series adds necessary code to support horizontal
output layout configuration using weston's config
file.

The output placement is relative to an output that
specifies outputs it should be placed next to, either
left of, or right of a given output. If there's a
conflicting output on that position, it's moved to
right.

For detailed information on the implementation, read
the patches summary.

This series depends on recently sent output configuration
API series, which I believe should be ready for landing [1].
You can find everything in the git repository [2].

Being in RFC stage, no documentation has been added
yet untill we can agree on an approach.

The code has been tested using DRM, Wayland and X11
backend, with the following config file options used
for WL/X11 backends (just change WL -> X for X11 backend):

[output]
name=WL0

[output]
name=WL1
left-of=WL0

[output]
name=WL2
right-of=WL0

[output]
name=WL3
left-of=WL2
right-of=WL5

[output]
name=WL4
left-of=WL3

[output]
name=WL5
