+ 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.
