*   NAME
*	LT_GetCode -- Easy raw key event to ANSI conversion.
*
*   SYNOPSIS
*	Key = LT_GetCode(Qualifier,Class,Code,Gadget);
*	 D0                  D0     D1    D2    A0
*
*	LONG LT_GetCode(ULONG,ULONG,UWORD,struct Gadget *);
*
*   FUNCTION
*	The user interface layout engine can convert IDCMP_RAWKEY
*	events into ANSI codes. Pass in the data you copied from
*	the IntuiMessage here.
*
*   INPUTS
*	Qualifier - Copied from IntuiMessage->Qualifier
*
*	Class - Copied from IntuiMessage->Class
*
*	Code - Copied from IntuiMessage->Code
*
*	Gadget - Copied from IntuiMessage->IAddress
*
*   RESULT
*	Key - ANSI code generated from the input data
*	    or -1 if no such code was to be generated.
