:: Bitmap image tracing utility

Options: -h, --help Print help text

File Options:

   -i, --input FILEPATH   The file path to use for input
   -o, --output FILEPATH  The file path to use for writing

Tracing Behavior:

   -m, --mode MODE          The method used for tracing the image in [OUTLINE, CENTER], (defaults to CENTER).
   -z, --turnpolicy POLICY  Method for extracting outlines
                            [BLACK, WHITE, MAJORITY, MINORITY], (defaults to MAJORITY).

Curve Evaluation Options:

   Parameters controlling curve evaluation behavior.

   -e, --error PIXELS      The error threshold (defaults to 1.0)
   -t, --simplify PIXELS   Simplify polygon before fitting (defaults to 2.0)
   -c, --corner DEGREES    The corner threshold (`pi` or greater to disable, defaults to 30.0)
   --optimize-exhaustive   When passed, perform exhaustive curve fitting (can be slow!)

Output Options:

   Generic options for output (format agnostic).

   -s, --scale SCALE    Scale for output, (defaults to 1).
   -p, --passes PASSES  Write extra debug passes,
                        comma separated list of passes including [PIXEL, PRE_FIT], (defaults to []).

TODO

While the basics work, currently there are areas for improvement.

Support for multiple image formats (most likely using the piston crate).
Improve bitmap outline extraction method.
Improve center-line extraction method.
