The engine expected all files listed in the detection entries to be resource
files. This commit adds the option to use a non-resource file for detection.
This is needed to use a MID file to detect one of the Windows versions of
Inherit the Earth.
This commit adds separate detection entries for the Windows and Linux versions
of Inherit The Earth.
There was a combined DOS/Windows/Linux entry with DOS as the platform. It is
not clear to me if this is a combined release or a single entry for three
separate releases, but the Windows and Linux release do exist as separate
releases. These would be detected with DOS as the platform, which would cause
the music not to work, because the DOS, Windows and Linux versions use
different music formats.
This function supported loading alternative bdf fonts when we were
using 8 bits encodings for the translations. Now that we are using
unicode for all language, this is no longer needed.
This was only used to be part of the name under which loaded TTF
fonts are stored in the FontMan font map. But since all the
languages now use the same charset (UTF-32), there is no longuer
a need to include the charset in the name. We still need to
differentiate between bdf fonts that can only be used for English
and TTF fonts, but this is is the case due to the font size being
included in the name. And otherwise we could just add a hardcoded
"-ttf" in the name.
We used to have different charsets depending on the language and
a different set of fonts for each one. So themes could support
some language and not others depending on the fonts it contained.
Now all languages are using UTF-32, except English. So the only
case that can fail is when not using English and the Theme does
not have TTF fonts.
The OpenGLSDLGraphicsManager was changed in bb15133a0a to use
SDL_WINDOW_FULLSCREEN_DESKTOP instead of SDL_WINDOW_FULLSCREEN.
But getFeatureState(kFeatureFullscreenMode) was still checking
the SDL_WINDOW_FULLSCREEN flag. This worked because in current
SDL2 versions SDL_WINDOW_FULLSCREEN_DESKTOP is defined as
SDL_WINDOW_FULLSCREEN | 0x00001000, but this is not documented
and could change in future SDL versions.
