+/* stbiw-0.92 - public domain - http://nothings.org/stb/stb_image_write.h
+   writes out PNG/BMP/TGA images to C stdio - Sean Barrett 2010
+                            no warranty implied; use at your own risk
+
+
+Before #including,
+
+    #define STB_IMAGE_WRITE_IMPLEMENTATION
+
+in the file that you want to have the implementation.
+
+
+ABOUT:
+
+   This header file is a library for writing images to C stdio. It could be
+   adapted to write to memory or a general streaming interface; let me know.
+
+   The PNG output is not optimal; it is 20-50% larger than the file
+   written by a decent optimizing implementation. This library is designed
+   for source code compactness and simplicitly, not optimal image file size
+   or run-time performance.
+
+USAGE:
+
+   There are three functions, one for each image file format:
+
+     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
+     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
+
+   Each function returns 0 on failure and non-0 on success.
+   
+   The functions create an image file defined by the parameters. The image
+   is a rectangle of pixels stored from left-to-right, top-to-bottom.
+   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
+   per channel, in the following order: 1=L, 2=LA, 3=RGB, 4=RGBA. (L is
+   luminance, i.e. monochrome "color", i.e. grey value.) The rectangle is
+   'w' pixels wide and 'h' pixels tall. The *data pointer points to the
+   first byte of the top-left-most pixel. For PNG, "stride_in_bytes" is
+   the distance in bytes from the first byte of a row of pixels to the
+   first byte of the next row of pixels. Other file formats assume the
+   first byte of the each row of pixels begins immediately after the last
+   byte of the previous row.
+
+   PNG creates output files with the same number of components as the input.
+   The BMP and TGA formats expand Y to RGB in the file format. BMP does not
+   output alpha.
+   
+   PNG supports writing rectangles of data even when the bytes storing rows of
+   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
+   by supplying the stride between the beginning of adjacent rows. The other
+   formats do not. (Thus you cannot write an in-memory BMP through the BMP
+   writer, both because it is in BGR order and because it may have padding
+   at the end of the line.)
