Description philipp.lohmann 2006-04-07 13:58:15 UTC 
With the integration of issue 61841 we integrated querying the system on a per
font basis whether to use antialiasing or embedded bitmaps. This querying was
implemented with a quadratic algorithm: for each found font a new pattern was
created that was applied to the whole set of found fonts.

This was unnecessary since we could add the property to the original object set
query.

Comment 5 caolanm 2006-04-20 12:00:50 UTC 
I suspect this might actually disables the functionality of issue 61841. I bet
it always says that embeddedbitmap and antialias are "unset", See issue 64508
Comment 6 philipp.lohmann 2006-04-24 08:29:01 UTC 
Maybe, but the FcConfigSubstitute for every font costs me 15 seconds on EVERY
startup, now that i have some 2000 fonts installed for testing reasons. I'd
rather live without the embed hint than have that penalty.

If fontconfig does not fill in that information that it promises, than perhaps
fontconfig should be fixed.
