The functions loader_C and loader_Croot provably did not do anything
besides returning an error, so removing them was safe.
For loader_Lua, this was using luaL_loadfile. But that in turn now
uses Sword25FileProxy, which only supports loading config.lua,
and config.lua is not used via the loadlib mechanism.
Therefore, I deemed it safe to also remove this third loader.
This leaves loader_preload as only remaining loader. It is probably
unused, too, but I did not both to investigate further, as I already
achieved my primary goal (getting rid of fopen/fclose use).
All other removed functions were unused due to the removal of the
first three loader_* functions.
This just uses the provided filename rather than trying to recreate
it with a hard-coded target (causing crashes with other targets).
(Also, add an error check rather then crashing there, just in case.)
This is needed now, since changing the language in-game updates the ScummVM language setting, and there must be a matching detection entry for each language.
The trydecpoint() function *is* used, though probably only in
countries which don't use a decimal point. We can't use the ISO C
locale functions here because they're not fully implemented on
some platforms, e.g. Android. Hopefully this method will work.
This unifies the engine names in MetaEngine::getName() and the
credits. In particular drop "Engine" or "engine" from the names when
it was present and use expanded names in credits when the
MetaEngine uses it (e.g. "Beneath a Steel Sky" instead of "BASS").
- Savegame thumbnails are now created using a flat image format,
instead of PNG. This allows us to remove the PNG encoding code used
in the engine. Note that the saved games we create cannot be used
with the original engine anyway, so this change does not break
savegame compatibility with the original game (it's already broken).
- Compatibility is preserved with older saved games that were made with
ScummVM.
- Moved the embedded thumbnail reading code out of the PNG loader class,
to stop it from needlessly checking every PNG file.
- With this change, libpng is no longer required for the sword25 engine
