 *      To reduce the size of the widget DLL, it is

 *      In addition, instead of linking frequently
 *      used helpers against the DLL again, we import
 *      them from XFLDR.DLL, whose module handle is
 *      given to us in the INITMODULE export.
 *
 *      Note that importing functions from XFLDR.DLL
 *      is _not_ a requirement. We only do this to
 *      avoid duplicate code.
 *
 *      For each funtion that you need, add a global
 *      function pointer variable and an entry to
 *      the G_aImports array. These better match.
