canvas:
  * show/hide
  * rename "bounds" signals
  * make the "path" vfunc of the CcShape a signal so people can post-process it,
    fix the bounds function to use path

demo:
  * show/hide demo

doc:
  * implement a script that checks for missing get_type() functions in ccc.types
  * implement a script that checks the ccc-sections.txt file

tests:
  * add a CcTestView that renders into a GdkWindow so we can safely emit events
    from there
  * add a test that makes sure that a new canvas gets displayed with the right
    adjustments
  * Add some generic tests that can be applied to all classes implementing a
    certain interface
  * analyse test coverage: http://check.sourceforge.net/doc/check.html/Determining-Test-Coverage.html#Determining-Test-Coverage

checks:
  * make sure that documentation/test coverage doesn't get worse when merging
    a branch
  * make sure the license is correct in any place (examples, lib, tests)
  * make sure timeouts are saved and (if necessary) removed
