is this enough of the directory that it'd be cleaner to just exclude the files
that are incompatible with ozone (or rename those files to end with _x11 if that
automatically excludes them)?

[kpschoedel, 2014/04/30 18:23:32]

The X11 dependencies are being isolated and/or removed in crbug.com/354034 (CL
248343002 in progress) and crbug.com/360377 (soon). I'll add the corresponding
gyp changes to for event_rewriter.* to the former, and rename
system_key_event_listener.* and xinput_hierarchy_changed_event_listener.* if
they still need to exist after the latter.
