Alpha modifier used when the ALPHA_MULTIPLY or ALPHA_OVERRIDE bits are set. The output alpha
value will either be replaced (ALPHA_OVERRIDE) or scaled (ALPHA_MULTIPLY) when enabled in the
ALPHA_CNTL field.

Indicates that colorkey functionality is enabled for this overlay. Pixels found in the overlay colorkey range
will be displayed as transparent (the S0 pixel will be used).
Determines how the alpha value is constructed for this overlay. Indicates that the value in the ALPHA field
should be used instead of the alpha values present in the input pixels.

ARGB8888 — 32-bit pixels with alpha
RGB888 — 32-bit pixels without alpha (unpacked 24-bit format)
ARGB1555 — 16-bit pixels with alpha
RGB565 — 16-bit pixels without alpha
RGB555 — 16-bit pixels without alpha
Embedded — Indicates that the OL pixel alpha value will be used to blend the OL with S0.The ALPHA
field is ignored.
Override — Indicates that the value in the ALPHA field should be used instead of the alpha values
present in the input pixels.
Multiply — Indicates that the value in the ALPHA field should be used to scale all pixel alpha values.
Each pixel alpha is multiplied by the value in the ALPHA field.
ROPs — Enable ROPs. The ROP field indicates an operation to be performed on the overlay and S0
pixels.
