+ * Sometimes we treat GLfloats as GLints.  On x86 systems, moving a float
+ * as an int (thereby using integer registers instead of FP registers) is
+ * a performance win.  Typically, this can be done with ordinary casts.
+ * But with gcc's -fstrict-aliasing flag (which defaults to on in gcc 3.0)
+ * these casts generate warnings.
+ * The following union typedef is used to solve that.
