Bug 1546139 - Restore the call to AdjustFixedOrStickyLayer() for layers fixed to the RCD-RSF. r=kats This call served two purposes: (1) scroll the fixed layer by the eVisual transform, and (2) adjust it by the fixed margins. The first purpose is now served by applying the eVisual transform to the async zoom container, but we still need the call for the second purpose.

 * This file is designed to be included into the file that provides the
 * nsIModule implementation for a particular widget toolkit.
 * The following functions are defined:
 *   nsAppShellInit
 *   nsAppShellShutdown
 *   nsAppShellConstructor
 * The nsAppShellInit function is designed to be used as a module constructor.
 * If you already have a module constructor, then call nsAppShellInit from your
 * module constructor.
 * The nsAppShellShutdown function is designed to be used as a module
 * destructor.  If you already have a module destructor, then call
 * nsAppShellShutdown from your module destructor.
 * The nsAppShellConstructor function is designed to be used as a factory
 * method for the nsAppShell class.
