if a line wrap or truncation happens how can I get the column number
relative to the beginning of the line displayed? for example:
-------------------------------------------------------------
This is a a loooooooooooooooooooooooooooooooooooooooooog line
start of the continuation <!> line
-------------------------------------------------------------
If point stays at <!>, some function `current-screen-column' should
return the relative column number to "start".
Is there any function available like count-screen-lines does but
calculates column number?
