Details:

This is a first attempt at implementing the roipoly function.

The function works in two modes:
- When three arguments are passed (img, xv, yv), rasterize the polygon
  delimited by the (xv, yv) points into an image with the same
  dimensions as img.
- When a single argument is passed (img), display the image in a new
  figure and let the user interactively select the (xv, yv) coordinates
  before performing the rasterization.

The interactive GUI is currently extremely simple: left click to add a
point, middle click to suppress the last point and right click to
terminate the interactive session.
