This FXG sub-compiler is similar to the MXML sub-compiler but it instead of compiling FXG documents as MXML it creates a display list based on optimized SWF graphics primitives. The root DefineSprite is linked to a generated ActionScript class using SymbolClass. A two-pass compile is still required to resolve dependent types and participate in the top level driver, i.e. CompilerAPI.
Since <TextGraphic> cannot be fully represented using SWF tags, additional ActionScript classes will be generated to programmatically instantiate instances of RichText and link them to a DefineSprite in the appropriate location in the SWF primitive display list.
