We have logic that detects when the same run of text is repeatedly painted and cache the result of shaping in a GlyphDisplayListCache entry. With GPU Process DOM rendering enabled, replaying that entry still results in significant IPC traffic, since we must send the vectors of glyph IDs and advances as part of the DrawGlyphs display list item.
We can turn these vectors (and perhaps the other DrawGlyphs members apart from the font resource ID) into a cacheable resource that the GPU Process can store.
