openjazz: Renders in monochrome

[smcv]

Prerequisites:

• Debian testing (Debian 12 alpha)
• Video: GNOME 43 in Wayland mode (with Mesa 22.2.0 on AMD Vega, if it matters)
• Audio: Pipewire 0.3.59, with pipewire-pulse emulating PulseAudio
• apt install openjazz game-data-packager
• game-data-packager -i jazz-jackrabbit (installs a demo version of the required data)
• Some relevant libraries:
  • libsdl1.2-compat either 1.2.58-1 (packaged in Debian experimental) or commit 63e4393 (locally built)
  • libsdl2-2.0-0 version 2.24.1+dfsg-1

To reproduce:

• OpenJazz /usr/share/games/jazz-jackrabbit-hh95
• LD_LIBRARY_PATH=.../sdl12-compat/_build OpenJazz /usr/share/games/jazz-jackrabbit-hh95
• SDL_VIDEODRIVER=wayland LD_LIBRARY_PATH=.../sdl12-compat/_build OpenJazz /usr/share/games/jazz-jackrabbit-hh95

Expected result: all work

Actual result: real SDL 1.2 works as expected, sdl12-compat renders in monochrome similar to #246

This broke with 9da8808c03e80a228ee66a714091249f331ebcd7, so clearly my understanding of SDL 1.2 palette management is not correct. I'll look into this further.

This one should be fixed by 35488c6 ?

Also: Did 35488c6 not bring back #216?

Also: Did https://github.com/libsdl-org/sdl12-compat/commit/35488c6894cb55ae4019392022c418f54dc3eb42 not bring back https://github.com/libsdl-org/sdl12-compat/issues/216?

It did, I just hadn't reopened it yet. :)

Confirmed fixed as of https://github.com/libsdl-org/sdl12-compat/commit/67f8b3a85b782eefb4db90f34d5b0742ef2cb5fc (1.2.58 + 29 commits)
