+		The result is a Dict with the screen position of the text
+		character in window {winid} at buffer line {lnum} and column
+		{col}.  {col} is a one-based byte index.
+		The Dict has these members:
+			row	screen row
+			col	first screen column
+			endcol	last screen column
+			curscol	cursor screen column
+		If the specified position is not visible, all values are zero.
+		The "endcol" value differs from "col" when the character
+		occupies more than one screen cell.  E.g. for a Tab "col" can
+		be 1 and "endcol" can be 8.
+		The "curscol" value is where the cursor would be placed.  For
+		a Tab it would be the same as "endcol", while for a double
+		width character it would be the same as "col".
+
 screenrow()							*screenrow()*
 		The result is a Number, which is the current screen row of the
 		cursor.  The top line has number one.
