GlyphData
The glyphs of one glyphs presenter (field-presentation §FVE-12, §FVG-9), built on the thread pool and carried to the worker as TetRenderData is. Immutable once built: a consumer detects a change by pointer.
In the namespace construct::asset. Declared in src/libs/libconstruct/construct/asset/FieldGlyphs.hpp.
