Which also allows the internals to be a bit simpler / potentially more
efficient, as the implementation can now access the glyph cache contents
directly, without a getter.
The new API makes it possible to alias storage for the glyph offsets,
advances and IDs (20 bytes per glyph) directly with the output positions
+ texcoords (16 bytes per glyph, times four) by splitting the retrieval
in two steps.
I wonder how long will it take before this bites back, heh.
In basically all cases it's two independent operations so forcing them
to be done together doesn't really bring any potential efficiency
advantages. On the other hand, splitting them allows allows the caller
to better make use of available memory, as the new
renderGlyphQuadsInto() allows the input and output arrays to be aliased.
Bumping AbstractFont plugin interface versions as this is a breaking
change.
The awful original STL-heavy public API is kept the same for now, it's
just the internals being now implemented using brand new APIs that are
actually usable with multiple fonts, font sizes and runs with different
scripts/languages/directions. There's also preparation for configurable
vertical text layouting, although for now the functionality asserts that
horizontal text is used.
This also makes Renderer.h header available on non-GL builds, as the new
APIs don't rely on a class full of GL objects anymore. The class will
get eventually renamed and moved to a dedicated RendererGL.h header, but
for now this partial update has to suffice.
So it's possible to shape the text even before having all glyphs ready.
That's one reason, second reason is that this is a more common behavior
-- it usually doesn't make sense to make the text jump based on whether
it's "zaxaca", "KEKEKE" or "yqpyq".
The original alignment based on glyph bounds is now moved into dedicated
`*GlyphBounds` variants. Additionally the `*LeftGlyphBounds` were
changed to subtract the initial glyph offset as well, `*Integer` now
rounds only in the direction where it's needed because a division by 2
happened, and there's a set of `*Bottom*` values that somehow weren't
there before.
It doesn't need to access anything else than what the base API provides,
doesn't render with it, and doesn't expose the instance via any getter
either.
Even though the Renderer is scheduled for a total rework and changing
the old API may feel like throwaway work, this change alone doesn't
break anything and allows me to test certain new corner cases.
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).
Partially needed to avoid build breakages because Corrade itself
switched as well, partially because a cleanup is always good. Done
except for (STL-heavy) code that's deprecated or SceneGraph-related APIs
that are still quite full of STL as well.
Instead make use of the ArrayView STL compatibility. To avoid breaking
almost all existing code the Corrade/Containers/ArrayViewStl.h header is
included implicitly when MAGNUM_BUILD_DEPRECATED is defined, but this
will get removed in some future release to speed up the compilation.
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.
103% of use cases use the returned value directly without checking, so
we might as well do the check ourselves. Added new function hasCurrent()
and added deprecated backward-compatibility conversion and -> operators.
Wow, that creeped to a lot of places.
Last dinosaur from the pointer age.
`char*` is now the default type for byte arrays. Results in shorter
code, less annoyances and more convenient testing. As is the case with
Corrade, I'm not doing any compatibility/deprecation layer, as most of
these functions is not widely used anyway.
The indexed binding is allowed for only some types (atomic counters,
uniforms, shader storage and transform feedback), thus we need separate
enum for that. Because the bind() function will be used far more often
than setTargetHint(), the original Target enum is now renamed to
TargetHint and the new Target enum contains (in non-deprecated build)
only three values.
For backwards compatibility, though, we need to have all original Target
values, thus the new Target enum contains also all other values from
TargetHint, but they are marked as deprecated and (at least) run-time
checked in bind() so they aren't accidentaly used for indexed binding.
Similarly there are also deprecated Target overloads of Buffer() and
setTargetHint(). It's ugly, but hopefully will suffice for now. This mess
will be removed as soon as possible in some upcoming version.
Only one value from these two was used in the end, wasting precious
bytes. Also these two values were used to differentiate between indexed
and non-indexed mesh (instead of relying on actual index buffer being
bound), which was very confusing. This approach looks more clean. The
MeshView class is not yet updated, as the change would expose some
features that aren't possible in current implementation (base vertex
specification).
Merged Mesh::setVertexCount() and Mesh::setIndexCount() into one
Mesh::setCount(), the two original functions are now guarded aliases to
the new one, are marked as deprecated and will be removed in future
release, similarly for the getters.
In particular, if the mesh is indexed, setVertexCount() does nothing and
vertexCount() returns 0. The setIndexCount() and indexCount() do and
return the same regardless of whether the mesh is indexed or not.
Each texture has slightly different usage requirements and having
everything under one generic class is not worth the additional runtime
checks and whatnot. The current way with Texture::Target enum
(hopefully not too widely used) is now deprecated and will be removed in
some future release. However general Texture1D/2D/3D usage is not
changed in any way.
The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
Take text size into account when advancing lines. I would probably not
run into this issue if I would visually test this on anything else than
unscaled pixel art font.
Because we can't forward-declare class members we would need to include
whole Mesh (along with all OpenGL headers and other stuff) just to use
Primitive enum. The old Mesh::Primitive is now alias to new one, is
marked as deprecated and will be removed in future release.
