Shouldn't be hard to add oblique matching. We skipped this because older API's didn't distinguish between italic/oblique but I think DirectWrite and fontconfig do, so it would be good to add this to the style matching code.

Tracked for 41 to ensure both italic and oblique styles render properly.

John, I am trying to follow up on FF41+ tracked bugs. Is this something that you are considering fixing for 41? If yes, it would be good if the patch is ready and uplifted by Beta6. Beyond that it would be tough to take any fixes unless the end-user impact is very high. Thanks.

The use of the fontconfig platform fontlist is disabled for beta/release builds so this should not be tracked for FF41.

FF41- based on comment 8. It is still tracked for 41. Perhaps someone should start investigating soon while 42 is in Aurora cycle.

(In reply to Sylvestre Ledru [:sylvestre] from comment #10) > John, is it also disabled in 42? Thanks Nothing at this point has changed, beta/release builds do not use the fontconfig platform fontlist path. I have a patch for this in progress so when this should already be fixed whenever we remove the beta/release restriction.
