Fixes the display position of the options using a plugin command.

Information about the position fixation is included in the save data.

About the Y Coordinate Type
The Y coordinate of the options is normally determined based on the position
of the message window.
To fix the options to a position corresponding to the top, middle, or bottom
of the message window,
select Top, Middle, or Bottom.

@command fixChoiceListPosition
@text Fixed position of options
@desc Fix the display position of the options.
@arg xPositionType
@text X coordinate type
@desc Specifies the type of X coordinate.
@type select
@default 4
@option left
@value 0
@option Medium
@value 1
@option right
@value 2
@option Numerical specification
@value 3
@option Not fixed
@value 4

@arg x
@text X coordinate
@desc Specifies the X coordinate. This is only valid when the X coordinate type is specified as a number.
@type number
@default 0

@arg yPositionType
@text Y coordinate type
@desc Specifies the type of Y coordinate: Top, Middle, or Bottom, which represents the location of the message window.
@type select
@default 2
@option above
@value 0
@option Medium
@value 1
@option under
@value 2
@option Numerical specification
@value 3
@option Not fixed
