The displayMode word bits are defined as:
Bit 0 selectedIconBit 1 = invert image before copying
Bit 1 openIconBit 1 = copy light-gray pattern instead of image
Bit 2 offLineBit 1 = AND light-gray pattern to image being copied
Bits 3-7 reserved.
Bits 8-11 foreground color to apply to black part of black & white icons
Bits 12-15 background color to apply to white part of black & white icons
Bits 0-2 can occur at once and are tested in the order 1-2-0.
"Color is only applied to the black and white icons if bits 15-8 are not all 0.
Colored pixels in an icon are inverted by black pixels becoming white and any
other color of pixel becoming black."
