Pango and OSX 10.4

[John Ralls <jralls ceridwen fremont ca us>]

I maintain a build framework for GTK+-2 on OSX which uses Quartz,  
rather than X11, as the display engine. (More info at http://gtk-osx.sourceforge.net 
) This is possible in part due to the excellent work of the pango team.

A recent change to Pango, 01783de926a09dd8a3b11699bc8b1a6b6dce0556,  
replaced ATS with CoreText. While this is necessary for x86_64  
compilation (ATS is Carbon and so only 32-bit compatible), it isn't  
backward-compatible with 10.4 (CoreText was introduced in 10.5). Since  
there are still a lot of Tiger users out there, it seems a bit  
premature to cut them off. Is this an intended consequence?

Regards,
