/**
* Native bindings to stb_image_write.h from the stb library.
*
* ABOUT
*
* This header file is a library for writing images to C stdio.
*
* The PNG output is not optimal; it is 20-50% larger than the file written by a decent optimizing implementation; though providing a custom zlib compress
* function (see {@link #stbi_zlib_compress zlib_compress}) can mitigate that. This library is designed for source code compactness and simplicity, not optimal image
* file size or run-time performance.
*
* USAGE
*
* There are five 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);
* int stbi_write_hdr(char const *filename, int w, int h, int comp, const void *data);
* int stbi_write_jpg(char const *filename, int w, int h, int comp, const float *data, int quality);
*
* void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
*
* There are also five equivalent functions that use an arbitrary write function. You are expected to open/close your file-equivalent before and after
* calling these:
*
*
* int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes);
* int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
* int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
* int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
* int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
*
* where the callback is:
*
*
* void stbi_write_func(void *context, void *data, int size);
*
* You can configure it with these global variables:
*
*
* int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE
* int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression
* int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode
*
* 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 {@code comp} channels of data stored interleaved with 8-bits per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is monochrome
* color.) The rectangle is {@code w} pixels wide and {@code h} pixels tall. The {@code *data} pointer points to the first byte of the top-left-most
* pixel.
