It was pointed out to me on IRC that some SDL 1.2 extension libraries
might not have an SDL 2 equivalent yet, or they might not be in Debian.

For example hex-a-hop can use SDL_ttf or SDL_Pango. Pango is a more
featureful text renderer, so the Debian package uses it. There is an
SDL2_Pango project available on GitHub but it isn't in Debian yet.

Looking through the packages, these appear to be missing:

   console kitchensink pango sge sound

Perhaps there are better equivalents for these in SDL 2 though?

Will the SDL team be packaging available SDL 2 equivalents for
the SDL 1.2 extension libraries that are in Debian?

I tested hex-a-hop under GNOME Wayland. It segfaults with SDL 1.2 and
SDL_VIDEODRIVER=wayland but does not with the SDL 1.2 compat lib via
LD_PRELOAD. When using the compat lib via LD_PRELOAD, the X11 mode has
a window title bar and border but those are missing in Wayland mode.

   dpkg-architecture -c sh -c 'LD_PRELOAD=/usr/lib/${DEB_HOST_MULTIARCH}/sdl12-compat/libSDL-1.2.so.0 hex-a-hop'
