* This terminal driver supports:
* Amiga Custom Screen
*
* AUTHORS
* Carsten Steger
*
* Pat R. Empleo Slightly modified for Aztec C v5.2a (beta); sort of
* 08/27/91 supports overscan; for large WB 2.0 virtual screens,
* we limit the plot size so we don't have to scroll
* around (not fun).
*
* Carsten Steger Modified to support Kickstart 2.0.
* 09/11/91 Opens a text overscan screen when used with WB 2.0.
* Discerns between NTSC and PAL Amigas when used with
* WB 1.3 and lower.
*
* Pat R. Empleo Defined some 2.0 stuff in order to get Aztec C to
* 09/20/91 work with Carsten's new code (see above). When
* KS/WB 2.0 support gets implemented in Aztec C, this
* kludge will get deleted!
* (Aztec C release 5.2 beta)
*
* Carsten Steger Converted to new terminal layout.
* 10/01/95
*
* Lars Hecking Add code from George Coulouris <glc5@cornell.edu> to
* 06/20/97 implement window option, requires AmigaOS 3.0+.
* General cleanup, better readability.
*
* Lars Hecking Replace static arrays for AMIGA_FontName and temporary
* 06/21/97 arrays with AllocMem()'d memory.
*
* send your comments or suggestions to (gnuplot-info@lists.sourceforge.net).
