masking is a technique for drawing shape or rendering image clipping in another shape. The way to mask is very similar to use drawing api as seen in sample #03, it differs by using set_mask and take care to the queue used to populate swf with tags. Object that will "mask" has item ID lower than the masked objects, but it must set a number of z-depth (the argument passed to set_mask) higher to the subsequents items id.
