- * bytes for each clip level. It could be done more
- * efficently per-object basis - but to make clipping
- * universal, there is no alternative to double
- * buffering (although it should be done into RGBA
- * buffer by other method than ::render to make global
- * opacity possible).
- * Using art-render could possibly optimize that a bit,
