Evas: Add "no-render" flag for proxy sources & clippers

Those objects should never be rendered on the canvas, even if they
are visible. On the other hand, they need to be rendered in mask or
proxy surfaces.

note: this patch includes some extra whitespaces changes :(

+        Setting the no_render flag on an object will make it never render
+        directly on the canvas, regardless of the visible and color properties.

+        required if it is a proxy source or a mask (clipper).
