Update to v106r41 release.

byuu says:

Changelog:

  - hiro: added Label::set(Background,Foreground)Color (not implemented
    on Cocoa backend)
  - hiro: added (Horizontal,Vertical)Layout::setPadding()
      - setMargin(m) is now an alias to setPadding({m, m, m, m})
  - hiro/Windows: update Label rendering to draw to an offscreen canvas
    to prevent flickering
  - sfc: reverted back to 224/240-line height (from 223/239-line height
    in earlier v106 WIPs)
  - bsnes: new multi-segment status bar added
  - bsnes: exiting fullscreen mode will resize and recenter window
      - this is required; the window geometry gets all scrambled when
        toggling fullscreen mode
  - bsnes: updated to a new logo [Ange Albertini]

Errata:

  - hiro/Windows: try to paint Label backgroundColor quicker to avoid
    startup flicker
      - `WM_ERASEBKGND` fallthrough to `WM_PAINT` seems to work
  - hiro/Qt: use Window backgroundColor for Label when no Label
    backgroundColor set
  - bsnes: update size multipliers in presentation.cpp to 224/240 (main
    window size is off in this WIP)
