org.apache.flex.swf.types.StyleChangeRecord
The style change record is also a non-edge record. It can be used to do the following:
1. Select a fill or line style for drawing.
2. Move the current drawing position (without drawing).
3. Replace the current fill and line style arrays with a new set of styles.
Because fill and line styles often change at the start of a new path, it is useful to perform more than one action in a single record. For example, say a {@code DefineShape} tag defines a red circle and a blue square. After thecircle is closed, it is necessary to move the drawing position, and replace the red fill with the blue fill. The style change record can achieve this with a single shape record.

            if (shape instanceof StyleChangeRecord)
