 Core wayland protocol
 
- - We need rotation information in the output (multiples of 90
-   degrees) and we'll need a way for a client to communicate that it
-   has rendered its buffer according to the output rotation.  The
-   goal is to be able to pageflip directly to the client buffer, and
-   for that we need the client to render accordingly and the
-   compositor needs to know that it did.
-
- - Atomicity.  Currently a lot of the atomicity in Wayland relies on
-   how we batch up all requests in a protocol buffer and only flushes
-   in the "blockhandler" in the client.  Consensus was that we need
-   something more reliable and explicit.  The suggestion is that we
-   make surface.attach a synchronization point such that everything
-   before that is batched and applied atomically when the
-   surface.attach request comes in.  For cases where we need atomicity
-   beyond a surface.attach, we can add an atomic grouping mechanism,
-   that can group together multiple surface.attach requests into a
-   bigger atomic change.  To be researched a bit.
-
- - We should make pointer sprites regular surfaces.  Something like
-   input_device.set_sprite(surface).  This also make client side
-   animated cursors simple/possible, since we now get a frame event
-   that can drive the animation.
-
  - Maybe try to make remote wayland actually happen, to see if there
-   is something in the protocol/architecute that makes it harder than
+   is something in the protocol/architecture that makes it harder than

- - Key events need a bit more work/thinking/redesign. As it is we need
-   a mechanism to change and synchronize keymaps, repeat rates.  But
-   as we started talking, we decided that we needed to go back and
-   research what other systems do instead of just essentially copying
-   the X model.  Sending out unicode events in addition to keycode
-   events has a lot of benefits (OSK can send out unicode events
-   instead of fake keycode events, apps become much simpler...)  Move
-   keymap handling and repeat to the server?  Needs more research.
-
- - Pointer axis events need modifiers (ctrl-scroll eg), but we either
-   need to send the modifier state with each axis/scroll event or send
-   keys down on pointer_focus and subsequent key events... or just key
-   events for modifier keys... or for the non-repeating subset?
-
- - Add timestamp to touch_cancel, add touch id to touch_cancel (?)
-
- - The output protocol needs to send all the ugly timing details for the modes.

- - clipboard manager interface?  what's needed?  just notification
-   that the selection has gone away.  should the clipboard manager be
-   able to take over the selection "seamlessly", ie, with the same
-   timestamp etc?  Doesn't seem like we need that, the clipboard will
-   have to set a new data_source anyway, with the subset of mimetypes
-   it offers (the clipboad manager may only offer a subset of the
-   types offered by the original data_source)
-
-   The trouble is that when the clipboard manager sets a new data
-   source, we don't want to renew the timestamp and potentially reject
-   a newer "real" data source.
-
  - mime-type guidelines for data_source (ie, both dnd and selection):
    recommended types for text or images, types that a clipboard
    manager must support, mime-types must be listed in preferred order
