+	Glyphs represent a run length encoded set of pixels for a 2
+	dimensional region of a plane.
+
+	x, y: The minimum x and y coord of the region in pixels.
+
+	w, h: The width and height of the region in pixels.
+
+	samples: The sample data. The sample data is in a compressed
+	format designed to give reasonable compression, and to be fast
+	to plot from.
+
+	The first sizeof(int) * h bytes of the table, when interpreted
+	as ints gives the offset within the data block of that lines
+	data. An offset of 0 indicates that that line is completely
+	blank.
+
+	The data for individual lines is a sequence of bytes:
+	 00000000 = end of lines data
+	 LLLLLL00 = extend the length given in the next run by the 6 L
+		bits given here.
+	 LLLLLL01 = A run of length L+1 transparent pixels.
+	 LLLLLE10 = A run of length L+1 solid pixels. If E then this is
+		the last run on this line.
+	 LLLLLE11 = A run of length L+1 intermediate pixels followed by
+		L+1 bytes of literal pixel data. If E then this is the
+		last run on this line.
