DESCRIPTION
The ImageByteOrder macro specifies the required byte
order for images for each scanline unit in XY format
(bitmap) or for each pixel value in Z format.
The BitmapBitOrder macro returns LSBFirst or MSBFirst
to indicate whether the leftmost bit in the bitmap as
displayed on the screen is the least or most
significant bit in the unit.
The BitmapPad macro returns the number of bits that
each scanline must be padded.
The BitmapUnit macro returns the size of a bitmap's
