- """Handle the "stop after" checkbox.
-
- The user wants the machine to pause after this patch. This can
- be useful for applique and similar on multi-needle machines that
- normally would not stop between colors.
-
- In most machine embroidery file formats, there's no such thing as
- an actual "STOP" instruction. All that exists is a "color change"
- command.
-
- On multi-needle machines, the user assigns needles to the colors in
- the design before starting stitching. C01, C02, etc are the normal
- needles, but C00 is special. For a block of stitches assigned
- to C00, the machine will continue sewing with the last color it
- had and pause after it completes the C00 block. Machines that don't
- call it C00 still have a similar concept.
-
- We'll add a STOP instruction at the end of this color block.
- Unfortunately, we have a bit of a catch-22: the user needs to set
- C00 (or equivalent) for the _start_ of this block to get the
- machine to stop at the end of this block. That means it will use
- the previous color, which isn't the right color at all!
-
- For the first STOP in a given thread color, we'll need to
- introduce an extra color change. The user can then set the correct
- color for the first section and C00 for the second, resulting in
- a stop where we want it.
-
- We'll try to find a logical place to split the color block, like
- a TRIM or a really long stitch. Failing that, we'll just split
- it in half.
