1554193 - Move support for the AAT 'trak' table from the macOS backend to platform-independent font code

Status: RESOLVED FIXED

(Core :: Graphics: Text, enhancement)

Description

[Jonathan Kew [:jfkthame]]

As a followup to bug 1553889, now that harfbuzz handles shaping of AAT fonts, we should move the support for the AAT tracking table ('trak') from the Mac backend over to our generic font code, so that such fonts will be handled the same on all platforms.

This will also allow us to eliminate the gfxMacFont override of ShapeText altogether once we remove the Core Text shaper (which we just preffed off, in preparation for removal).
