commit 1838412121d0bac8ce443d362e75439d58a93a4d

Define new manual-redirect clipping semantics and bump version to 0.4.
Manual-redirect windows no longer clip their parents, nor do they affect
expose event computation. This makes it possible to create application-level
composited windows which can be damaged by other window manipulations.
This patch also removes the coordinate transformation stuff which was never
released.

+Version 0.4 of the protocol changes the semantics of clipping in the

+With version 0.4, the parent is no longer clipped to child windows which are

without using

- 'count' indicates the number of events still to be delivered for
- 'window' to satisfy a particular operation within the server
-
- The client must respond to this event with a suitable
- TransformCoordinate request that includes matching 'window', 'child'
- and serialNumber fields.

- 'serialNumber' may be repeated in multiple events, indicating that
- the server needs to redo the same transformation for some reason.
