The hb_font_t object holds on to tables of font data, acquired through the MinikinFont::GetTable interface, which is based on copying data into caller-owned buffers. Now that we're caching lots of hb_font_t's, the cost of these buffers is significant. This patch moves to a different interface, inspired by HarfBuzz's hb_reference_table API, where the font can provide a pointer to the actual font data (which will often be mmap'ed, so it doesn't even consume physical RAM). Bug: 27860101 Change-Id: Id766ab16a8d342bf7322a90e076e801271d527d4
