 Source/Render/DX9/RendererDX9.cpp, ...

Batch #10843 by ragnarok-clanker: 2 byte-identical, 2 confirmed by peer review.

- fn_45506 DeviceOwnerDX9::CaptureBackBuffer: byte-identical (annotation added to existing code)
- fn_45507 DeviceOwnerDX9::RestoreBackBuffer: byte-identical (annotation added to existing code)
- fn_45508 ReleaseApplicationCursor: logic confirmed by peer review
- fn_06367 ApplyServiceOptionCursorClip: logic confirmed by peer review

Peer-reviewed-by: dori, cremane, StrawberrysherbetIX
Accepted without human review: peers confirmed the logic ("same" ahead by at least 3, with 70% of the votes).
