WRaster context depth 24.
  (styleoffsets::::::): do not guess offsets for miniwindow and
  appicon they are equal to 0.0.

  (_handleTakeFocus:forContext:): if application (window) receives
  WM_TAKE_FOCUS in hidden state it means WindowMaker wants us to be
  unhidden.

  Description: There are 2 protocols defined in XGServerWindow.h:
  WMFHideApplication and WMFHideOtherApplications. These protocols exist
  to help GNUstep application and WindowMaker notify each other
  about "Hide" and "Hide Others" actions. There are no protocols for
  "unhide" action.

  Test case steps:
  1. Open application with window opened.
  2. Hide application with "Hide" menu item.
  3. Open WindowMaker's "Windows" menu (middle-click on desktop).
  4. Select hidden application window.
  Application unhides, activates, restored window is focused (receives) input
  and "Hide" menu item unselected.
