Draws a portion of an image transformed to fit into a parallelogram specified by the Points parameter
The Points parameter must have a length of 3 to specify the coordinates of the upper-left corner, upper-right corner, and lower-left corner of the parallelogram. The coordinate of the lower-right corner is calculated using the three given coordinates, the width, and the height of the image. The portion of the source image to be drawn is scaled to fit the parallelogram.
