Details

In a tp2 profile, ATSUMatchFontsToText is taking up a huge amount of time (25-30% of the total time in one profile).  The amount of time used seems excessive, even accepting that tp2 triggers fallbacks a lot more than normal pages.
While bug 396732 is more focused on binary-as-text, the root cause is the same as this, we're spending a lot of time doing font matching via ATSUMatchFontsToText.  The plan is to fix this by porting over the Windows font matching code, bug 396137.
