PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide

/* sproutline - v0.10 - public domain sprite outline detector - http://github.org/ands/sproutline
no warranty implied; use at your own risk
Do this:
#define S2O_IMPLEMENTATION
before you include this file in *one* C or C++ file to create the implementation.
// i.e. it should look like this:
#include ...
#include ...
#include ...
#define S2O_IMPLEMENTATION
#include "sproutline.h"
You can #define S2O_MALLOC to avoid using malloc
QUICK NOTES:
Primarily of interest to game developers.
- Recommended to be used with stb_image.
- Detects outlines in sprite images with alpha channels.
- Extracts outlines as clockwise paths.
- Simplifies outlines based on a distance metric.
Full documentation under "DOCUMENTATION" below.
Revision 0.10 release notes:
- Initial release of sproutline.h.
- Added S2O_MALLOC macro for replacing the memory allocator.
Unlike most STB libraries, this macro doesn't support a context parameter,
so if you need to pass a context in to the allocator, you'll have to
store it in a global or a thread-local variable.

// DOCUMENTATION
//
// Limitations:
// - currently only works with images that have alpha channels
//
// Basic usage (with stb_image):
// int w, h, n, l;
// unsigned char *rgba = stbi_load(filename, &w, &h, &n, 4);
// unsigned char *alpha = s2o_rgba_to_alpha(rgba, w, h);
// unsigned char *thresholded = s2o_alpha_to_thresholded(alpha, w, h, ALPHA_THRESHOLD);
// unsigned char *outlined = s2o_thresholded_to_outlined(thresholded, w, h);
// s2o_point *outline = s2o_extract_outline_path(outlined, w, h, &l, 0);
// while(l)
// {
// s2o_distance_based_path_simplification(outline, &l, DISTANCE_THRESHOLD);
// // ... process outline here ...
// // ... l = number of points in outline
// // ... ALPHA_THRESHOLD = 1..255 (the min value to be considered solid)
// // ... DISTANCE_THRESHOLD = 0.0f..Inf (~0.5f is a suitable value)
// // ... a greater value results in fewer points in the output
//
// outline = s2o_extract_outline_path(outlined, w, h, &l, outline);
// };
// free(outline);
// free(outlined);
// free(thresholded);
// free(alpha);
// free(rgba);
//
// s2o_rgba_to_alpha:
// Expects an 'unsigned char *' to memory of w * h 4-byte pixels in 'RGBA' order.
// The return value is an 'unsigned char *' to memory of w * h 1-byte pixel alpha components.
//
// s2o_alpha_to_thresholded:
// Expects an 'unsigned char *' to memory of w * h 1-byte pixel alpha components.
// The return value is an 'unsigned char *' to memory of w * h 1-byte values
// that are 255 if the corresponding input is >= the specified threshold, otherwise 0.
//
// s2o_thresholded_to_outlined:
// Expects an 'unsigned char *' to memory of w * h 1-byte pixels indicating their solidity {0, nonzero}.
// The return value is an 'unsigned char *' to memory of w * h 1-byte pixels that indicate if the
// corresponding input value is part of an outline (= is solid and has a non-solid neighbour).
//
// s2o_extract_outline_path:
// Expects an 'unsigned char *' to memory of w * h 1-byte pixels indicating their outline membership.
// The return value is an 's2o_point *' to memory of l s2o_point values consisting of a short x and y value.
// The procedure scans the input data from top to bottom and starts extracting the first outline it finds.
// The pixels corresponding to the extracted outline are set to 0 in the input, so that a subsequent call to
// s2o_extract_outline_path extracts a different outline.
// The length is set to 0 if no outline was found.
//
// s2o_distance_based_path_simplification:
// Expects an 's2o_point *' to memory of l outline points.
// The procedure throws out points in place that lie on or close to linear sections of the outline.
// The distanceThreshold parameter specifies the min distance value for points to remain in the outline.
//
// ===========================================================================
//
// Philosophy
//
// This library is designed with the stb philosophy in mind.
// stb libraries are designed with the following priorities:
//
// 1. easy to use
// 2. easy to maintain
// 3. good performance
//
// Some secondary priorities arise directly from the first two, some of which
// make more explicit reasons why performance can't be emphasized.
//
// - Portable ("ease of use")
// - Small footprint ("easy to maintain")
// - No dependencies ("ease of use")
