26670 - need to remove the slow pref enumeration in font engine

Status: RESOLVED WONTFIX

(Core :: Layout, defect, P3)

Description

[Erik van der Poel]

Troy pointed out that the font pref enumeration that we are currently doing
when the font for the document's language group does not contain a glyph for the
current character is really slow. We should remove the call to that enumerator
and do it in a better way, possibly by hard-coding the language groups, since
we're already hard-coding them in the font enumerator (for font prefs UI)
anyway. Or try to find an extensible way to do that. Also, instead of some
random order for those languages, it might be a good idea to try the user's
language first. (Remember, this is *after* the document's language has failed.)

Prioritizing my bugs. It is not worth changing this until it actually shows up
on the performance radar, i.e. in Quantify's output. Therefore M20.

No No No. That was not part of the deal. You were supposed to fix the problem, 
not try to ignore it and wait for me to prove its a performance problem.

Even if that code only executes once, it's inefficient. And if it's never 
executed, then it's dead code and should be removed. BTW, that's my solution to 
how to fix the problem...

Do we still need to do this? Move it to future for now. If we need to deal with 
it, we should split it into two bugs- one for window and one for linux.
