SDL_ttf v. 2.24 has renamed the internal _TTF_Font struct to TTF_Font 1 (the v3 branch also introduced this in v. 3.1.2 2).

This breaks the build at least for current NixOS iterations; cf. this build output:

commandergenius: fix broken build due to renamed _TTF_Font struct i…
5cc6a94 
…n SDL_ttf

SDL_ttf renamed the internal `_TTF_Font` struct in v. 2.24 [^1] and
3.2.2 [^2], breaking current builds for commandergenius.

Upstream already merged my pull request fixing the error [^3].
This pulls in the fix temporarily using `fetchpatch`; as soon as
upstreams a new release, we'll likely be able to remove it again.
