Can you give me suggestion how to get y > location of cursor even when when (window-hscroll) is large? I need to see an example of a situation where you cannot get the Y coordinate of the cursor due to a large window-hscroll. Is it at all an interesting situation, or just a theoretical one? Also, if you just use frame-char-height in that case, does that solve the problem?
