Incremental Transfer Demo

Proof of concept implementation of an incremental transfer system using HarfBuzz subsetting (hb-subset) combined with a well-known patch algorithm. State is entirely transient; refresh to reset. We do lots of woefully inefficient things; demonstrating speed is NOT the point.

Transfer Configuration

Note the version of harfbuzz subsetting used in this demo does not yet support layout table subsetting or subsetting variation tables.

Coming soon: Brotli Patch Mode.

Transfer Options

NOTE: all options other than incremental transfer break layout features across segments. In reality this forces the use of large blocks in many scenarios (Arabic, Indic, many latin cases, etc).
