Position

  Position of requesters

  Unchanged - requesters will behave exactly the same as with the old
 version of asl.

  Mouse  Pointer  -  requesters will be open under the mouse pointer.
 If pointer is near the edge of the screen it may be not-so-perfect.

  Center  In Window - requesters will be centered in respect to their
 parent  window.   If  no parent window was specified in requester's tags by
 the  programmer,  the  requester will be treated as though Center On Screen
 was active.

  Center  On Screen - requesters will be centered in respect to their
 parent  screen.   If  no parent screen was specified in requester's tags by
 the programmer, the requester will be centered on its parent window's
 screen. If parent window was not specified either, the requester will be
 centered on the default public screen.

  Top Left of Window - requesters will be open in the top left corner
 of  their  parent window.  It falls to the same actions as Center In Window
 if programmer didn't specify the necessary tags.

  Top Left of Screen - requesters will be open in the top left corner
 of  their  parent screen.  It falls to the same actions as Center on Screen
 if programmer didn't specify the necessary tags.


   Finally,  please  note that all size/position calculations are in respect
 to  the  visible part of the virtual screens and also requester always open
 to be entirely visible.
