+/*!
+ This class is a helper class with static-only methods for accessing various
+ meego graphics system functionalities. The way it works is that the helper

+ expected to make sure that you're indeed running with 'meego' before using any
+ of the specialized methods. 
+
+ In example:
+
+ \code
+ QPixmap p;
+ if (QMeeGoGraphicsSystemHelper::isRunningMeeGo()) {
+    p = QMeeGoGraphicsSystemHelper::pixmapWithGLTexture(64, 64);
+ } else {
+    p = QPixmap(64, 64);
+ }
+ \endcode
+
+ Calling any of the meego-specific features while not running meego might
+ give unpredictable results. The only functions safe to call at all times are:
+
+ \code
+ QMeeGoGraphicsSystemHelper::isRunningMeeGo();
+ QMeeGoGraphicsSystemHelper::runningGraphicsSystemName(); 
+ QMeeGoGraphicsSystemHelper::switchToMeeGo();
+ QMeeGoGraphicsSystemHelper::switchToRaster();
