 The bit mask can be used for much more than bit-aligned fonts. For

 useful for drawing the edges of primitives, such as filled polygons,
 that potentially involve modifying some but not all of the pixels

 Basically, the bit mask is handy whenever only *some* of the eight
 pixels in a byte of display memory need to be changed, because it allows

 processing, which from a performance perspective would be undesirable
