e_mod_rotation_wl: doing rotation if ec is obscured by 32bit opaque window

There was a bug that below window didn't rotation under 32bit colored upper window changed from opaque to transparent.

The rotation activate trigger is uniconify rendering. (emits e,visibility,prepare,foreground signal)
The above window doing opaque_set -> opaque_unset, and The below window turns FULLY_OBSCURED -> UNOBSCURED.

But the below window is still uniconic state and didn't uniconify rendering, caused by the above window is 32bit colored and opaque state.
So, after the below window turn to UNOBSCURED, it still rotation deactivated.

To solve this problem, if the window is uniconic state, doing rotate under bg_client even if it is fully obscured window.

NOTE:: If above 32-bit opaque window draws translucent buffer, then below window may appear unrotated if below window has parent ec.
