History
William Wilgus 660fa3ffdc scroll engine calculate stringsize only when scroll line updated 
we calculate the size of the scrolling line every scroll update
the line data doesn't ever change without a call to update
instead calculate the string size when the line is updated
re-use this value while scrolling the line

in theory the current font could change but in practice
I can't find a case when the string size needs to be updated
that the scroll engine isn't already updating the line

if this is later an issue we can recalculate the stringsize each time
the line is finished scrolling which still saves quite a few calculations

Other:
I don't think we have any targets with pixel counts exceeding 65535 pixels
where unsigned short stringsize will be an issue
