#16254: MYST3: Widescreen Mod now overwrites values stored in
last_window_width/height.

    Type:  defect         |     Status:  new
Priority:  normal         |  Component:  Engine: Myst3
 Version:                 |   Keywords:
    Game:  Myst 3: Exile  |
--------------------------+---------------------------
 Tested with recent macOS Master builds from Buildbot:
 - Intel x86 build on an Intel Mac running macOS 10.6.8 & 10.11.6,
 - Apple Silicon build on a MacBook Air running macOS 15.7.

 This is one of 3 inappropriate changes observed in Myst3 since the merger
 of the 3D & 2D Graphics Managers.

 When Myst3 is launched with its Widescreen Mod enabled, the window is
 reconfigured from a 4:3 to 16:9 configuration (853x480 when in windowed
 mode). Usually, if this modified window is created in windowed mode, the
 values stored in last_window_width/height aren't adjusted, ensuring the
 modified window doesn't persist after exiting the game.

 However, this has now changed. Creating this window in windowed mode now
 overwrites the last_window_width/height values, which converts the
 expected 4:3 window used by the Launcher and other games to this 16:9
 configuration.

 The resizing issue in #16253 can hide this behaviour, but it can be
 confirmed by launching Myst3 in windowed mode, then exiting back to the
 Launcher.

 From an OpenGL (with or without shaders) perspective, this issue affects
 all macOS versions listed above, but doesn't exist in the 2.9.1 macOS
 releases.

 However, this issue already exists in the 2.9.1 & earlier macOS releases
 if using the Software 3D Renderer.

 Having said that, the Software renderer doesn't handle the Widescreen Mod
 properly, setting up the 16:9 window with a 4:3 image to the left, and an
 empty area to the right, in both fullscreen and windowed modes, so it's
 not currently viable for use with Myst3.
