 Support for Wayland with QmlCompositor as Server
================================================

The Wayland video driver has support for some additional features when
using QtWayland's "qmlcompositor" as Wayland server. This is needed for touch
input when running SDL applications under a qmlcompositor Wayland server.

The files following headers have been
generated from the Wayland XML Protocol Definition in QtWayland as follows:

Clone QtWayland from Git:
    http://qt.gitorious.org/qt/qtwayland/

Generate headers and glue code:
    for extension in touch-extension surface-extension windowmanager; do
        wayland-scanner client-header < src/extensions/$extension.xml > wayland-qt-$extension.h
        wayland-scanner code < src/extensions/$extension.xml > wayland-qt-$extension.c
    done
