The recognition algorithm always works on a bitmap of set and unset (foreground and background) pixels. The debug image used to show the input image after image processing, but if the processing did not include a command that replaced pixels with fore- or background pixel values, it would not show which pixels are foreground, and which are not. This commit uses the make_mono() function to create the debug image, thereby creating a representation of the bitmap used for recognition.
