> BMP files with negative bitmap height are not supported

> 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.
