1135308 - add pref for explicitly disabling downloadable font cache

Status: RESOLVED FIXED

(Core :: Graphics: Text, defect)

Description

[John Daggett (:jtd)]

In the course of trying to reduce the dumping of textruns for pages that use downloadable fonts, I realized it would be helpful to have a pref that allows the downloadable font cache to be bypassed. Fonts downloaded without caching will go through the same code flow that would occur with an uncached font, making it easier to catch errors during the reflow.

Attachment: patch, add pref to allow downloadable font cache to be disabled

Simply disable downloadable font cache insertions and lookups based on a pref.
