I'm working from an example from the 5 1/2 blog on that uses
the DisplacementMapFilter to create a trapezoid transformation.
Basically, it makes a movieclip look like it has perspective. I'm
having a difficult time trying to get the movieclip to scale and
keep the distortion after applying the filter. What happens is, the
movieclip will scale, but if, for example, I'm scaling larger but
only the top left section of the movieclip, which fits to the
dimensions of the displacement map, are distorted. I think the
displacementmap graphic needs to be scaled as well, but I'm not
sure how to do that?
if it's not "drawn" from a movieclip, then attach it to a
movieclip, and create a new bitmap using the draw method to copy
the movieclip to the bitmap. you can apply scaling (using the
matrix parameter) in the draw method.
