In both cases, +ensure that the \c{lib} and \c{includes} paths include the OpenGL ES +headers and libararies from your SDK. The OpenGL ES lib should be called +either \c{libGLES_CM.lib} for the Common profile or \c{libGLES_CL.lib} for +the Common Lite profile. + +The distinction between the Common and Common Lite profiles is important, +because the Common Lite profile has less functionality and only supports a +fixed-point vertex format. + +To start programming with Qt and OpenGL ES on Windows CE, you can start +with the \l{Hello GL ES Example}. This example shows how to use QGLWidget +and QGLPainter with OpenGL ES. It also provides some hints on how to port +OpenGL code to OpenGL ES. + +\section2 Using OpenGL to Accelerate Normal 2D Painting + +Qt provides QOpenGLPaintEngine, a subclass of QPaintEngine that translates +QPainter operations into OpenGL calls. This is especially convenient for +drawing text or QImage objects in an OpenGL ES context. For further +details, refer to the \l{Hello GL ES Example}. + +*/
