fonts
Supplies immutable resource-pack font definitions and files instead of the compatibility ASCII mask declarations. The snapshot can be shared between profiles and hosts and owns no native state. A host using this profile must supply its independently owned font backend through the font-aware host factory.
Parameters
snapshot
complete immutable font resource state, pinned until a new profile and host are created.
Throws
when fonts or any compatibility glyph were already declared.
after the callback returns or from another thread.
