Patch release for 2.3 that fixes some incorrect behavior:

• Heretic: Sky textures are only partially visible.
• Hexen: Sky textures are sized incorrectly.
• Alignment of floor/ceiling textures whose size is not 64×64.
• macOS: Missing and flickering textures on M1 Macs.
• macOS: Bullets firing in the wrong direction on M1 Macs.
• macOS: 3D camera mode does not allow flying downwards, only upwards on M1 Macs.

Note that the macOS build is still for Intel so it will run under Rosetta.
