Suppress embedding fonts when the skp's fonts match the OS fonts.
The million SKPs generated require >5T of storage. A good deal of that are copies of system fonts. Chrome built with #DEFINE SK_WHITELIST_SERIALIZED_TYPEFACES will omit the font data if the font matches a precomputed checksum. The captured SKP prepends sk_ to the names of fonts that have their data omitted. The SKP consumer can either add renamed fonts from the recording machine, or add gDeserializeTypefaceDelegate = WhitelistDeserializeTypeface; which strips the sk_ prefix when deserializing typefaces. whitelist_typefaces --check Computes the checksums of fallback fonts and returns 0 if the checksums match the checked-in file SkWhitelistChecksum.cpp. whitelist_typefaces --generate Writes an updated version of SkWhitelistChecksum.cpp. (Added Mike since this modifies a public header) R=bungeman@google.com,rmistry@google.com,reed@google.com Review URL: https://codereview.chromium.org/1317913005
