I'd like to be able to specify a floating point resource and use 
XtSetArg to modify it on the creation of a widget.  Thus:

	{ XtSomeResource, XtCSOMETHING, XtRFloat, sizeof(float),
		XtOffSet(Widget, thing.floating_field), XtRFloat, 
		(caddr_t)&def_float}

is my resource and I want to be able to say:

	XtSetArg(arg[n], XtSomeResource, 1.00); n++;
	XtCreateManagedWidget(..., arg, n);

and have my "thing.floating_field" field set to "1.00"

I've tried adding a class_init routine which does an

XtAddConverter(XtRFloat, XtRFloat, CvtFloatToFloat, NULL, 0);

but although this gets called, CvtFloatToFloat (which I've written)
is NEVER called.

Anyone have a clue as to what I've done wrong?

	Thanks,

		John
