> The BMP format allows for negative values of the height field in the header. This means
that the image lines are stored top-down, not bottom-up as usual (i. e. the first pixel in
the pixel array would be in the top left corner of the image, not in the bottom left as usual).
However, when a negative-height bitmap is passed, the BmpImageParser attempts to create an
array of negative length, and a NegativeArraySizeException ensues.
