+POPUP MASK						*popup-mask*
+
+To minimize the text that the popup covers, parts of it can be made
+transparent.  This is defined by a "mask" which is a list of lists, where each
+list has four numbers:
+    col		start column, positive for counting from the left, 1 for
+		leftmost, negative for counting from the right, -1 for
+		rightmost
+    endcol	last column, like "col"
+    line	start line, positive for conting from the top, 1 for top,
+		negative for counting from the bottom, -1 for bottom
+    endline	end line, like "line"
+
+For example, to make the last 10 columns of the last line transparent:
+	[[-10, -1, -1, -1]]
+
+To make the four corners transparent:
+	[[1, 1, 1, 1], [-1, -1, 1, 1], [1, 1, -1, -1], [-1, -1, -1, -1]]
