Subject: [PATCH] docs: Remove checks for whether an effect is disabled

pre_paint() and post_paint() implementations don't need
to check whether an effect is disabled: Clutter will
not apply an effect unless it is enabled.

So remove code which checks whether the effect is
enabled or disabled from the example applications and the
documentation.
