Description Simon Fraser (smfr) 2021-04-07 15:09:14 PDT 
Cached DisplayLists used in FontCacade use 1KB item buffers that only contain a single DrawGlyphs item, which is very wasteful. We should find a more compact way to store these.

Maybe we need different DisplayList storage for in-process vs IPC display lists.
