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 scanline unit in bits.
