It won't contain just font metrics anymore. Also don't require the
struct to be zero-initialized if opening fails -- simply allow the
plugins to return garbage in that case and save the values only if
opening actually succeeded.
Strictly speaking this isn't an ABI change as the return value isn't
part of the function signature and the struct is still the same, so the
plugin interface version isn't bumped for this change.
All std::string arguments are now a StringView, what returned a
std::pair is now a Pair. STL compatibility headers are included on
deprecated builds to ease porting, as usual.
The only *really* breaking changes are in the internals, where an
ArrayView<const char32_t> is used instead of std::u32string, which is in
line with the change done in Utility::Unicode::utf32(); and a Triple is
returned instead of a std::tuple. Behaviorally nothing changed except
that fillGlyphCache() now asserts if the input string contains invalid
UTF-8 (which is also in line with the cahnge done in Utility::Unicode).
Not that C++ STL and exceptions would be anything to take inspiration
from, but there's std::out_of_range. Python IndexError is also specified
as "index out of range", not "bounds".
About time this got done. This also has an XFAIL for the case where a
distance field image is processed with an offset, have to fix the
underlying issue in TextureTools first.
Also added a range assertion for the distance field image setter to
match what the abstract base does, together with a corresponding getter.
Of course I used the wrong `CORRADE_FAIL_IF(false, ...)` in a few
places. Yet another confirmation it was too hard to use and a dedicated
macro is needed.
Similar to the change done in Corrade, see the commit for details:

Wow, this is probably the most backwards-compatibility code I've ever
written. Can't wait until I can drop all that.
It limits the support for CMake 3.12+, but it's much less verbose and I
don't expect people to use ancient CMake versions with IDEs like Xcode
or VS anyway, so this should be fine.
Like in Trade, the unatomic exists() + read() pair (and silent failures
if the file exists but can't be read) was replaced with just
Path::read() that now returns an Optional. Besides that, not much worth
mentioning.
And clean up the noise from there. This is some very old code, so the
coverage was rather poor, including two uncaught bugs causing
test failures. Fixing that in the next commit.
Basically mirroring the API of Trade::AbstractImporter, as that proved
to be useful. The old crazy openSingleData() and openData(horribleStuff)
are deprecated and will be removed in a future release.
No backwards compatibility is provided for font plugins, these need to
be adapted.
Allows the Font and FontConverter plugins be built without TARGET_GL
enabled. That was the last piece missing for making the magnum-plugins
repo completely GL-free.
