Both {\VW} and {\DP} have a tendency to remove the small bends altogether, a

Sometimes low-water rivers in slender slopes have many bends next to each
|
||||
other. In low resolutions (either in small-DPI screens or paper, or when the
|
||||
river is sufficiently zoomed out, or both), the small bends will amalgamate to
|
||||
a unintelligible blob. Figure~\onpage{fig:amalgamate1} and
|

figure~\onpage{fig:amalgamate2} are real-world examples where a river, normally
|
||||
1 or 2 pixels wide, creates a few pixels wide blob due to a number of bends.
