811312 - remove ATS-based font code

Status: RESOLVED FIXED

(Core :: Graphics: Text, defect)

Description

[Jonathan Kew [:jfkthame]]

As 10.5 support has been dropped, we no longer need the ATS-based version of the font management code; we use the CG-based version on 10.6 and later. So we can rip out a bunch of obsolete code here.

Comment 1

[Jonathan Kew [:jfkthame]]

Attachment: This simply removes the ATSFontEntry class and all references to it in the Mac font code, as we never use it on 10.6+.

Comment 2

[Jonathan Kew [:jfkthame]]

Attachment: Having removed ATSFontEntry, we can then fold CGFontEntry into the MacOSFontEntry class; we no longer need the abstract superclass as we only have one concrete implementation of it.

Comment 3

[Jonathan Kew [:jfkthame]]

Attachment: part 2 - fold CGFontEntry subclass into MacOSFontEntry

Minor update - we can also drop the extra level of indirection in MakePlatformFont now that there's only one font entry class on the platform.
