pixel in the input image to produce a result with a new set of
RGBA color and alpha values.
ConvolutionFilter The ConvolutionFilter class applies a matrix convolution
filter effect.
DisplacementFilter The DisplacementMapFilter class uses the pixel values
from the specified BitmapData object (called the displacement
map image) to perform a displacement of an object.
DropShadowFilter The DropShadowFilter class lets you add a drop shadow
to display objects.

Modifying the filters of a display object or sprite is a three-step process:

1. Assign the sprite's filter to a temporary array.
2. Modify the temporary array the way you want, either remove an existing
filter or add an additional filter.
3. Assign the temporary filter back to the sprite's filter property, assuming that
m_filter was defined as follows:

private var m_filter:DropShadowFilter = new DropShadowFilter();

The following is the code to add a filter to the sprite m_sprite :

var filters:Array;
filters = m_sprite.filters;
filters.push(m_filter);
m_sprite.filters = filters;
