270154 - Use NSLayoutManager for text redering on Mac OS X

Status: RESOLVED WONTFIX

(Core Graveyard :: GFX: Mac, defect)

Description

[Katsuhiro MIHARA]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8a4) Gecko/20040927
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8a4) Gecko/20040927

In Mac OS X 10.2 or later, NSTypesetter encapsulates ATSUI
(But 10.2 lacks interfaces to override).
Applications can use NSTypesetter via NSLayoutManager.
If we use ATSUI for text redering (Bug 121540),
NSLayoutManager is an alternative.

But NSLayoutManager is a part of the Cocoa API.
I have no plan to move GFX code to the Cocoa API.
This report is a daydream.


Reproducible: Always
Steps to Reproduce:
1. launch Mozilla Suite, Camino,
   Mozilla Firefox, Mozilla Thunderbird.

Actual Results:  
Mozilla uses QuickDraw for text rendering.


Expected Results:  
If Mozilla uses NSLayoutManager,
Mozilla maybe render more beautiful text.

How does this interact with Cairo on OSX?

It's more likely we'll use ATSUI (bug 121540).
