;Description - Creates a LinearGradientBrush object from a set of boundary points and boundary colors.
; $aFactors - If non-array, default array will be used.
;           Pointer to an array of real numbers that specify blend factors. Each number in the array
;           specifies a percentage of the ending color and should be in the range from 0.0 through 1.0.
;$aPositions - If non-array, default array will be used.
;            Pointer to an array of real numbers that specify blend factors' positions. Each number in the array
;            indicates a percentage of the distance between the starting boundary and the ending boundary
;            and is in the range from 0.0 through 1.0, where 0.0 indicates the starting boundary of the
;            gradient and 1.0 indicates the ending boundary. There must be at least two positions
;            specified: the first position, which is always 0.0, and the last position, which is always
;            1.0. Otherwise, the behavior is undefined. A blend position between 0.0 and 1.0 indicates a
;            line, parallel to the boundary lines, that is a certain fraction of the distance from the
;            starting boundary to the ending boundary. For example, a blend position of 0.7 indicates
;            the line that is 70 percent of the distance from the starting boundary to the ending boundary.
;            The color is constant on lines that are parallel to the boundary lines.
