Re: Calculating screen relative X when horizontal scrolling.

[Keith David Bershatsky]

Amendment to prior email ...

Instead of:  "The first character 'の' which was at a relative_x of 55 in a 
(scroll-left 9) situation, is still at a relative_x of 55 in a (scroll-left 10) 
situation".

I should have said:  "The first character 'の' which was at a relative_x of 44 
in a (scroll-left 9) situation, is still at a relative_x of 44 in a 
(scroll-left 10) situation".
