Allows the OBJ to be flipped horizontally and vertically.
A normal display is produced by a setting of 0 and a flip display by a setting
of 1.
When the rotation/scaling flag ([d08] of OBJ Attribute 0) is enabled, these
bits also can be used as the high-order bits of the rotation/scaling
parameter selection.
[d13-09] Rotation/Scaling Parameter Selection
The parameters used in OBJ rotation/scaling processing are selected from
the 32 parameters registered in OAM.
