にも以下のような一文があります。

The Swing team is considering adding the option of creating InternalFrames
as heavyweight containers in a future Swing release to alleviate this  problem.
However, until then, adhere to the following guideline:

というわけで、考えられるアプローチは2つあるわけですね。
1. Offscreen rendering (by Java3D team)
2. Heavywaight InternalFrames (by Swing team)

どっちかってーと2が有り難いですけど、これってSwingの根っこから書き直す
ことになりそうな。。。

# InternalFrameの境界情報使って有効な描画領域を自分でクリッピング
# するというのは可能なのかな？？？
