This change includes the following scalability improvements for documents containing extremely large paragraphs: - Reduces the size of layout contexts to account for LF control chars. - Due to typical access patterns while laying out paragraphs, VCL was making O(n^2) calls to vcl::ScriptRun::next(). VCL now uses an existing global LRU cache for script runs, avoiding much of this overhead.
