Change telparia.com samples link to template

Effect2: Attributed the big block of text; replaced the Atari Forum Wiki link with Template:AtariForumWiki (left the Google Cache link there, but presumably that's going to disappear at some point itself)

'''Paintworks''' is a graphics program for the Atari ST published by Activision in 1986.

		+
		+	Early versions of Paintworks were called N-Vision. These are often mistaken as
		+	NEOchrome files. One should not rely on the file extension to determine the contents.
		+
		+	1 word file id [0x00]
		+	recommend using 'secondary file id' for identification
		+	1 word resolution [0 = low, 1 = medium, 2 = high]
		+	recommend using 'flags' to determine resolution
		+	16 words palette
		+	12 bytes file name, usually [" . "]
		+	1 word ?
		+	1 word ?
		+	1 word ?
		+	9 bytes secondary file id ["ANvisionA"]
		+	1 byte flags, bit field: cxrrtttt
		+	c = compression flag [1 = compressed]
		+	x = not used
		+	r = resolution [0 = low, 1 = medium, 2 = high]
		+	t = type [0 = page, 1 = screen, 2 = clipart, 4 = pattern]
		+	page = double high, thus 320x400, 640x400, 640x800
		+	screen = standard st resolutions
		+	clipart = standard st resolutions
		+	pattern = no documentation at this time
		+	64 bytes ?
		+	---------
		+	128 bytes total for header
		+
		+	? image data:
		+	Uncompressed images are simply screen dumps as one might expect.
		+
		+	Compressed images are a two step process, RLE decoding and re-ordering.
		+	RLE decompression:
		+
		+	/* Written by Lonny Pursell - placed in to Public Domain 1/28/2017 */
		+	void decode_rle(uint8 data, uint8 bmap, uint32 bms) {
		+	uint8 cmd, chr;
		+	uint16 i;
		+	uint32 src=0, dst=0, cnt=0;
		+	do {
		+	cmd = data[src++];
		+	if (cmd & 0x80) { /* literal? */
		+	cmd = cmd & 0x7f;
		+	memcpy(&bmap[dst], &data[src], (uint32)cmd);
		+	dst = dst + (uint32)cmd;
		+	src = src + (uint32)cmd;
		+	} else { /* repeat? */
		+	chr = data[src++];
		+	for (i=0; i<cmd; i++) {
		+	bmap[dst++] = chr;
		+	}
		+	}
		+	cnt = cnt + cmd;
		+	} while (cnt<bms);
		+	}
		+
		+	The uncompressed data is arranged as follows:
		+
		+	ST low resolution:
		+	All of plane 0..., all of plane 1..., all of plane 2..., all of plane 3...
		+	ST medium resolution
		+	All of plane 0..., all of plane 1...
		+	ST high resolution:
		+	No rendering required.
