Following the commits:

  c03544da - clutter-shader: use cogl_program_set_uniform_xyz API
  a26119b5 - tests: Remove use of cogl_program_use

Remove the users of cogl_program_uniform_* and cogl_program_use() in the
shader-based effects.

d10ebe9fca effects: Check before using the cogl_shader_* API
Since BlurEffect and DesaturateEffect are using the shader API
implicitly and not using ClutterShaderEffect, we need to check if the
underlying GL implementation supports the GLSL shading language and warn
if not.

1ec577438e desaturate-effect: Do not inherit from ShaderEffect
Hide the fact that we're using a fragment shader, in case we're able in
the future to use a material layer combine function when painting the
offscreen target texture.

8d51617979 Conditionally use g_object_notify_by_pspec
This adds a wrapper macro to clutter-private that will use
g_object_notify_by_pspec if it's compiled against a version of GLib
that is sufficiently new. Otherwise it will notify by the property
name as before by extracting the name from the pspec. The objects can
then store a static array of GParamSpecs and notify using those as
suggested in the documentation for g_object_notify_by_pspec.

Note that the name of the variable used for storing the array of
GParamSpecs is obj_props instead of properties as used in the
documentation because some places in Clutter uses 'properties' as the
name of a local variable.

Mose of the classes in Clutter have been converted using the script in
the bug report. Some classes have not been modified even though the
script picked them up as described here:

json-generator:

 We probably don't want to modify the internal copy of JSON

behaviour-depth:
rectangle:
score:
stage-manager:

 These aren't using the separate GParamSpec* variable style.

blur-effect:
win32/device-manager:

 Don't actually define any properties even though it has the enum.

box-layout:
flow-layout:

  Have some per-child properties that don't work automatically with
  the script.

clutter-model:

  The script gets confused with ClutterModelIter

stage:

  Script gets confused because PROP_USER_RESIZE doesn't match
  "user-resizable"

test-layout:

  Don't really want to modify the tests

fd27ca7398 Mark property strings for translation
Both the nick and the blurb fields should be translatable, for UI
builders and other introspection-based tools.

0e9a1dee6d shader-effect: Simplify setting the shader source
Sub-classes of ShaderEffect currently have to get the handle for the
Cogl shader and call cogl_shader_source(); this makes it awkward to
implement a ShaderEffect, and it exposes handles and Cogl API that we
might want to change in the future.

We should provide a ClutterShaderEffect method that allows to (safely)
set the shader source at the right time for sub-classes to use.

based on a controllable factor.
