This file was written by Edmund Mergl + * for his Amiga port of TeX 3.1 and MetaFont 2.7 from the original Unix + * sources (see Fish Disks 611-616). + * + * Some modifications and improvements were made since 1993 by Andreas and + * Stefan Scherer, Abt-Wolf-Strasse 17, 96215 Lichtenfels, Germany. The + * most recent entries from top to bottom always superseed their ancestors, + * just read this as a bit of history: + * + * August 12, 1993: + * + * - We use the `memory hack', so the values for `screenwidth' + * and `screendepth' are to be found in `mfmemory.config'. The + * display height should be set to an InterLace value, this will + * be dealt with by `lacefactor' (see below). + * + * - The display window is no longer resizeable, because no + * `screenupdate' is called and the picture is destroyed. + * + * - Based on ideas by Stefan Becker used in his famous MetaFont port + * to the Amiga of 1991 (see Fish Disk 486) there is a variable + * `scalefactor', which can be set to a (small) positiv integer in + * `mfmemory.config'. This results in a reduced size of the displayed + * characters, so that large font pictures can be drawn on + * small-sized screens (although some distortions are possible). + * + * - By replacing `Move' and `Draw' with `WritePixelLine' and friends + * the speed of the display was heavily increased. + * + * - The display screen is totally controlled by `screenwidth' and + * `screendepth' from `mfmemory.config', when you set `screen_rows' + * and `screen_cols' both to the maximum value `4095' in your local + * device modes file. MetaFont takes the smaller of these pairs. + * + * - `blankrectangle' *always* set the complete display window to the + * background color, not only the area specified by `left', `right', + * `top', and `bottom'. These MetaFont coordinates are now obeyed. + * + * September 11, 1993: + * + * - The changes for `Computers and Typesetting -- Volume A-E' provided + * by Addison-Wesley Publishing Company resulted in MetaFont 2.71. + * This caused a change in the window title. + * + * October 22, 1993: + * + * - The official version 2.71 has the same window title. :-) + * + * January 28, 1994: + * + * - Although SAS/C has an AutoOpen feature for Amiga libraries, + * it is better to define the library bases explicitly. + * + * February 15, 1995: + * + * - Here's my new address: + * Andreas Scherer, Rolandstraße 16, 52070 Aachen, Germany. + * <scherer@genesis.informatik.rwth-aachen.de> (Internet). + * - Make `amiga.c' compliant with the syntax of the other modules + * in the Web2C 6.1 distribution. + * + * February 19, 1995: + * + * - `close_all()' must not have arguments, because we want to + * link it into the `atexit()' function list. + * - To distinguish this version from the old distribution, the + * window title is modified. + * + * March 23, 1995: + * + * - MetaFont has the new version number 2.718. + * + * April 9, 1995: + * + * - rename `screenheight' to `screendepth' for consistency. + * + * October 10, 1995: + * + * - Yet another change in my address, now it's a UNIX CIP pool: + * <scherer@physik.rwth-aachen.de> + * - Cleanup for the new web2c release. + * + * January 20, 2010: + * + * - MetaFont has the new version number 2.718281. + */ + +#define EXTERN extern + +#include "../mfd.h" + +#ifdef AMIGAWIN /* Whole file */ + +#include <proto/exec.h> +#include <proto/graphics.h> +#include <proto/intuition.h> + +struct GfxBase *GfxBase; +struct IntuitionBase *IntuitionBase; + +struct Screen *Scr; +struct Window *Win; + +struct BitMap tempbm; +struct RastPort temprp; + +UBYTE *linearray; + +int scaledwidth = 0; +int scaledheight = 0; + +#ifndef scalefactor +#define scalefactor 1 +#endif + +/* + * The configuration `mf.mcf' of AmiWeb2C holds values for `screenwidth' + * and `screendepth' that always refer to an InterLace screen.
