+/**
+ * Documenting Bug 586
+ * 
+ * <p>
+ * JScrollPane cannot mix hw/lw components, only if setting property '-Dsun.awt.disableMixing=true'.
+ * </p>
+ * <p>
+ * You can use ScrollPane, or maybe a slider and fwd the panning to the GLCanvas,
+ * which could change it's GL viewport accordingly.
+ * </p>
+ * See git commit '8df12ca151dfc577c90b485d4ebfe491b88e55aa'.
