FSW is Formal SignWriting. It is a regular string built for display,
searching and sorting.

There are 2 parts to this string. The first part is the ordered prefix
for sorting, which is optional.

The "A" denotes the start of the ordered prefix. A list of ordered
symbols follows the "A". Sorting uses regular binary string comparison.
Any normal sort routine will work.
The second part of the string is the unordered detail for display.
The start of the string is "M", which stands for the middle lane. The
other possible values are "L" for left and "R" for right.
The symbols are positioned in 2 dimensional space with x,y values. The
numbers are separated by the letter 'x'. The coordinate space is
centered on the coordinate 500,500.
The first coordinate after the 'M' is the maximum coordinate of the
canvas (534x548) which is the bottom right.
Next comes the unordered symbols with coordinates for top-left positioning.

Symbol S20600 is positioned at 512,512
Symbol S30004 is positioned at 482,482
Symbol S18610 is positioned at 492,518
The minimum coordinate of the canvas is derived from the symbol
positions: 482,482. In this case, the values come from the same symbol,
but this is not always the case.
So the top-left of the canvas is coordinate (482,482). The bottom-right
of the canvas is (534,548). The center of the canvas is 500,500 by default.
So the canvas has a width of 534-482 = 52. And the canvas has a height
Hope that helps,
