|
|
; QuickGlue is the QuickDraw/Mac OS interface. It is linked with QuickDraw and
|
|
; defines all of the externals required by QuickDraw except those of the
|
|
; font manager. All of these are very short and simple (memory manager traps or
|
|
; jumps through the graphics jump table).
|
|
;
|
|
; Modification History
|
|
;
|
|
; 16-Nov-82 AJH Made font manager interface go through graphics jump table
|
|
; 09-Feb-83 AJH Added LockHandle, UnLockHandle
|
|
; 17-Aug-83 SC Made all cursor jumps preserve A0
|
|
; 22-Apr-85 LAK Removed RInitGraf (coordinated with Bill clearing
|
|
; QDExist flag in InitGraf).
