View Ref-File8.12  Graphics library                                             TOS

This library takes on the management of rectangles; so one can draw a 
rectangle that moves automatically with the mouse pointer, say. In 
all, the following functions are available:

 ∙ graf_dragbox      Moves a rectangular outline frame
 ∙ graf_growbox      Animates a growing rectangle
 ∙ graf_handle       Obtains ID of the AES workstation
 ∙ graf_mbox         Displays moving rectangle
 ∙ graf_mkstate      Obtains state of mouse pointer and keyboard
 ∙ graf_mouse        Alters appearance of mouse pointer
 ∙ graf_multirubber  Displays two 'rubber band' outline rectangles
 ∙ graf_rubbox       Display 'rubber band' outline rectangle
 ∙ graf_shrinkbox    Animates a shrinking rectangle
 ∙ graf_slidebox     Obtains slider position
 ∙ graf_watchbox     Selects an object and supervises mouse movements 
                     referring to this object
 ∙ graf_wwatchbox    Selects an object in a window and supervises 
                     mouse movements referring to this object.
 ∙ graf_xhandle      Obtains ID of the AES workstation

Note: Of these, graf_handle has earned special importance because with 
its aid the ID of the physical screen workstation can be obtained.
