Clutter libraries need update to v0.4 (from 0.2)

[Bob Spencer]

Binary package hint: libclutter-0.4

Proposed changes: This is a bug created for Feature Freeze Exception, to request that the clutter libraries be updated from v0.2 to v0.4. These include:
  clutter ( 0.2.3 already in gutsy. 0.4.2 requested)
  clutter-gst ( 0.1 already in gutsy, 0.4.0 requested)
  clutter-gtk ( 0.1 already in gutsy, 0.4.0 requested)
  clutter-cairo ( nothing in gutsy, 0.1 in feisty, 0.4.0 requested for gutsy)
  python-clutter (nothing in gutsy or feisty, 0.4.0 requested for gutsy)
The new versions of these projects are already in the debian unstable repository: http://packages.debian.org/search?keywords=clutter+0.4&searchon=names&suite=all&section=all

Potential impact on the distribution: clutter v0.4+ is backward compatible with v0.2. However, if there are other components in gutsy that use the clutter libraries, there is a potential that these components will break.

A rationale for the exception / benefit of the change: The ubuntu-mobile user interface makes use of OpenedHand's Clutter libraries. Some of the code depends on v0.4 of the libraries. Currently only v0.2 is part of gutsy. If the current version of the clutter libraries is not updated then some compromises will need to be made with regard to which Clutter features can be used. At a minimum the home screen will not be able to be based on the current Clutter code. One advantage Ubuntu has if it uses Clutter is to show potential customers a way to create rich graphical user interfaces using OpenGL.

Attached to this bug are files for each of the 4 projects above.

  <pkg>-pbuilder.log

Some notes: cairo is not in gutsy yet, so no diffstat or changelog.

As those are needed for Ubuntu Mobile and there are no rdepends outside of clutter-*, I think this can safely be approved.

Approved.

[Sebastien Bacher (seb128)]

I've synced those but due to a soyuz bug some uploads might now work (conflicting with existing ppa versions)

[Martin Pitt (pitti)]

clutter-gtk and python-clutter still need to be synced, rest has been done.

[Martin Pitt (pitti)]

clutter-gtk fake-synced, pyclutter is already in the archive.
