c69bb976b3 Annotate all public symbols
We are going to switch to compiler annotations to determine the
visibility of the symbols.

8b995a9457 clutter-shader-effect: Add a get_static_shader_source virtual
This is used as an alternative to calling
clutter_shader_effect_set_shader_source. A ClutterShaderEffect
subclass is now expected to implement this method to return the source
for the effect that will be used for all instances of this
subclass. It is only called once regardless of the number of instances
created. That way Clutter can avoid recompiling the shader source for
every new instance of the effect.

53483896a8 shader-effect: Allow instantiating ShaderEffect
ClutterShaderEffect doesn't require to be sub-classed in order to be
useful. It is possible to just create an instance, set the source and
the uniforms, and attach it to an actor. This should effectively replace
ClutterShader for good.

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.

c260da79e3 effect: Add ShaderEffect
The ShaderEffect class is an abstract base type for shader-based
effects. GLSL-based effects should be implemented by sub-classing
ShaderEffect and overriding ActorMeta::set_actor() to set the source
code of the shader, and Effect::pre_paint() to update the uniform
values, if any.

The ShaderEffect has a generic API for sub-classes to set the values
of the uniforms defined by their shaders, and it uses the shader
types we defined for ClutterShader, to avoid re-inventing the wheel
every time.
