Maps array of 2D points from image-relative to view-absolute coordinates. This does NOT take
into account the zoomable transformation. Points are represented by float array of [x0, y0, x1,
y1, ...].

@param destPoints destination array (may be the same as source array)
@param srcPoints source array
@param numPoints number of points to map
