Tomba! Recompiled v0.20.2-alpha

Tentative fix for horizontal tearing in focused fullscreen/borderless windows.
Please retest the same display and fullscreen settings used with v0.20.1.

• Preserve synchronized OpenGL swaps on faster displays while the wall-clock
  pacer keeps the original game speed. Previously a display refresh different
  from the game cadence disabled VSync even with frame blending turned off.
• Retire Tomba's Temporal Frame Blending package. It is removed from release
  catalogs, and its old activation IDs are inert so saved selections and older
  installed manifests cannot enable it again. This was image blending rather
  than true geometry interpolation.
• Preserve explicit VSync-off, existing interpolation scheduling in other
  titles, netplay pacing, and driver-recovery fallbacks.
• Keep the v0.20.1 adaptive widescreen camera fix and other visual mods.

Muted hidden-window Windows A/B checks reproduce swap interval 0 before and 1
after at a simulated 144 Hz refresh, with stock gameplay remaining near 59.94
frames/s. An old enabled blending manifest also stays on stock frames. These
checks establish runtime behavior; physical focused-fullscreen scanout tearing
still needs confirmation on the reporter's display.

Memory cards and settings carry over. CD Speed and host-paced Fast Loading
remain absent from both release packages.
