*
|
|
* A bitmap contains one bit for every pixel that defines if that pixel is

* black (1) or white (0). Bits within a byte are arranged vertically, LSB
|
|
* at top.
|
|
* The bytes are stored in row-major order, with byte 0 being top left,
|
|
* byte 1 2nd from left etc. The first row of bytes defines pixel rows
|
|
* 0..7, the second row defines pixel row 8..15 etc.
|
|
*
|
|
* This is the mono bitmap format used on all other targets so far; the
