Release of External Software Rendering for JPCSP

[iplayemugames]

I discovered another issue with FF4 CC affecting external software renderer exclusively. This one is not so serious as it doesn't hinder gameplay. It appears that the barrier around leading character is missing when stepping over a save point.
This is a common issue with PPSSPP. See: https://github.com/hrydgard/ppsspp/issues/4234
It has been stated in that issue report thread that the bezier / splines curves are to blame. The commit that caused the bug in PPSSPP is here: https://github.com/hrydgard/ppsspp/commit/2b66a85
I attached game save data for quick reproducing.
