-/* gdevdsp.h - callback structure for DLL based display device */
-
-#ifndef gdevdsp_INCLUDED
-#  define gdevdsp_INCLUDED
-
-/*
- * The callback structure must be provided by calling the
- * Ghostscript APIs in the following order:
- *  gsapi_new_instance(&minst);
- *  gsapi_set_display_callback(minst, callback);
- *  gsapi_init_with_args(minst, argc, argv);
- *
- * Supported parameters and default values are:
- * -sDisplayHandle=16#04d2 or 1234        string
- *    Caller supplied handle as a decimal or hexadecimal number
- *    in a string.  On 32-bit platforms, it may be set
- *    using -dDisplayHandle=1234 for backward compatibility.
- *    Included as first parameter of all callback functions.
- *
- * -dDisplayFormat=0                      long
- *    Color format specified using bitfields below.
- *    Included as argument of display_size() and display_presize()
- * These can only be changed when the device is closed.
- *
- * The second parameter of all callback functions "void *device"
- * is the address of the Ghostscript display device instance.
- * The arguments "void *handle" and "void *device" together
- * uniquely identify an instance of the display device.
- *
- * A typical sequence of callbacks would be
- *  open, presize, memalloc, size, sync, page
- *  presize, memfree, memalloc, size, sync, page
- *  preclose, memfree, close
- * The caller should not access the image buffer:
- *  - before the first sync
- *  - between presize and size
- *  - after preclose
- * If opening the device fails, you might see the following:
- *  open, presize, memalloc, memfree, close
- *
