Static Function RadialGradient ( X1 As Float, Y1 As Float, R1 As Float, X2 As Float, Y2 As Float, R2 As Float, Colours As Variant[], Positions As Float[] ) As PaintBrush

Create a new radial gradient paint brush.

It will interpolate colors between a start circle defined by ( X1, Y1, R1 ) and an end circle defined by ( X2 , Y2 , R2 ), and using color stops defined by the Colors and Positions arguments.

X1 : the x-axis coordinate of the start circle.
Y1 : the y-axis coordinate of the start circle.
R1 : the radius of the start circle. Must be non-negative and finite.
X2 : the x-axis coordinate of the end circle.
Y2 : the y-axis coordinate of the end circle.
R2 : the radius of the end circle. Must be non-negative and finite.
Colors : an array of color stops.
Positions : the position of each color, 0 being the gradient start, and 1 the gradient end.
