ArrayList appears to exist solely to have its minimum taken

[Kenneth Heafield]

The objlinetop object appears to exist as an ArrayList solely so that later code can take the minimum value.

Line 942 in c1d9f74

 minlinetop = Collections.min(objlinetop); 

Replace with a double and take the minimum on the fly. Same for many of the other objects in this function.

[Dion Wiggins]

Data is no longer kept in the collection as part of optimizations. The rewrite has removed this issue. Min value is calculated on the fly.
