+ *
+ * If you see garbage inside the ball as it is running rather than the red and yellow
+ * checkerboard pattern then the fast invsqrt() function in GMISC does not work on
+ * your processor.
+ *
+ * You can modify the implementation of invsqrt() by firstly defining
+ * 		#define GMISC_INVSQRT_MIXED_ENDIAN	TRUE
+ * in your gfxconf.h file.
+ *
+ * If it still doesn't work then instead define
+ * 		#define GMISC_INVSQRT_REAL_SLOW		TRUE
+ * in your gfxconf.h file. This should always work although it will probably be slow.
