The X.Y.Z version portion was unreliable, as it pulled from the latest tag regardless of platform. Set version to 0.0.0 and retrieve only the hash, which allows us to drop the node/npm dependency.
- Trim whitespace from labels before determining their max-width for alignment.
- Fix crash on labels that contain lines with only a single character of whitespace.
Continue to use uint32 as glyph ID to maintain Glyph PBF, even though we're only using 16 bits of that uint32.
Use std::codecvt instead of boost::unicode_iterator for UTF8->UTF16 conversions.
* [core] Line-break ideographic text by character
Allow a line break to be inserted after any supported Chinese, Japanese, or Yi character in a point-placed label. Balance the lines unless non-ideographic text such as Latin letters are present.
Fixes#1223.
* [core] Moved more character classing into util::i18n
* [core] Detect character properties by Unicode block
* [test] Reenabled ideographic breaking tests
* Extract `ignore` util to separate header.
* `Segment` now tracks offset and length of indices, rather than primitives. This is more natural.
* Introduce `VertexVector` and `IndexVector` types. These types carry information about the intended draw mode (`Triangles`, `LineStrip`, etc.), and ensure that elements are always appended in a group size appropriate for that draw mode, for both indexed and unindexed rendering.
* `Program`, rather than `Drawable`, is now the unifying object for draw calls. `Program` is the best place to type check the draw call, because it is typed to carry information about the intended primitive, vertex type, attributes, and uniforms.
* Use the debug shaders for debug tile rendering, like gl-js.
* Fix the draw mode for background. It was drawing triangle strips with a triangles array. Surprised this didn’t cause issues. Now it’s type checked.
This function can be called from different threads and was depending
on a global `std::string protocol` which can do heap allocations.
The first thread to use it would initialized it which is not exactly
safe, so this patch moves it to a `char *` that is just a pointer to
the data segment, so no races.
Valgrind detected it on #6431.
