QWS can be used with either of OpenGL-ES profiles subject to the
availability of Qt graphics driver plugin for your OpenGL Es
implementation.

This plugin, in most cases, is specific to the OpenGLES
implementation. For example, Qt comes with a driver plugin for OMAP3
OpenGL ES implementation.

For that you have to configure Qt with "-opengl es X" option and build
that driver plugin.

Yes.. as per trolls Lighthouse is the future of Qt windowing systems.
