meritous: Draws 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 meritous (Debian package version 1.5-1.1)
• 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:

• meritous
• LD_LIBRARY_PATH=.../sdl12-compat/_build meritous
• SDL_VIDEODRIVER=wayland LD_LIBRARY_PATH=.../sdl12-compat/_build meritous

Expected result: all work

Actual result: with real SDL 1.2, the menu is in shades of cyan and initial gameplay is in shades of blue. With sdl12-compat (either X11 or Wayland), both are in shades of grey.
