- * Invalidation Mechanism
- *

- * has been true for any part of the update rgn the background is erased in the entire region
- * not just in the specified rect.
- *
- * In order to achive this, we also have an internal m_macNoEraseUpdateRgn, all rects that have
- * the eraseBackground flag set to false are also added to this rgn. upon receiving an update event
- * the update rgn is compared to the m_macNoEraseUpdateRgn and in case they differ, every window
