Compared to Corrade, the improvement in compile time is about a minute
cumulative across all cores, or about 8 seconds on an 8-core system (~2
minutes before, ~1:52 after). Not bad at all. And this is with a
deprecated build, the non-deprecated build is 1:48 -> 1:41.
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".
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.
Interesting, didn't know this kind of feature support was possible. I
guess it's still better than no GLES3.2 at all. Also, it's a phone from
2017, so probably not all that important to care about anymore anyway.
Currently just the bare minimum, more features such as handling
multiple contiguous strips and loops inside a single mesh or an
overlapping layout will come later.
The shader requires the input data to be laid out in a rather specific
way, and there will be a dedicated MeshTools utility for it in the
following commits. For independence though, the shader tests use a
custom helper.
The initial implementation has certain corner cases which will be
eventually resolved. For now they are pinned down with repro cases in
the test. But apart from that, it's pretty much usable in practice.
Remaining join styles (round and miter-clip) as well as stipple support
will eventually follow as well.
