Purpose

This function writes out a 24-bit Windows bitmap file that is readable by Microsoft Paint.
The image data is a 1D array of (r, g, b) triples, where individual (r, g, b) values can
each take on values between 0 and 255, inclusive.

Arguments

Parameters
[in]filenamechar* A string representing the filename that will be written
[in]widthuint32 The width, in pixels, of the bitmap
