Window mode fixes TEST vs. LIVE

Hello everyone!

TEST fixes various known issues with LIVE's desktop/background/maximize/fullscreen image window modes when the window is locked. So here is some feedback, tests were done on Mac OS (Intel MBP 2018, Intel UHD Iris Plus 655 GPU) and desktop PC (Intel UHD 630 GPU and NVidia 2700). New PF2 campaign, Agents of Edgewatch AP1 module loaded, DP (1st Floor) map used.

- Lower right scroll button vanishing: fixed.

- Zoom level changing and zoom-to-fit not working: fixed.

- Extraordinary high Intel GPU load that could not even be fixed using /vsync 4: partially fixed.

The last one is only "partially" fixed, because LIVE starts using higher load (mostly Intel GPU), but there is an easy workaround for all the listed issues: resize the FG application window (back and forth). Once this workaround is applied then LIVE uses multiple factors lower GPU load than 03-31 TEST to display the same image (LOS enabled, Lighting disabled) in all window modes. Still nice to see the fixes.

Nice to hear! I've been seeing a lot of "resize the app and it fixes the problem" type workarounds posted for things (or maybe it's been the same issue I've seen in multiple places). Hopefully that whole class of issues can get worked out!
