[Freetype] FTC_ImageCache * and FTC_Image_Cache*

[Jungshik Shin]

Hi,

While trying to figure out why Mozilla doesn't make use of freetype 
printing code, I  found that FTC_Image_Cache* had gone (I updated 
freetype2 library a few days ago.) They are deprecated and I guess I 
have to fix Mozilla to use new APIs (FTC_ImageCache*). Before doing 
that, I'd like to know when (in what version of freetype2) 
FTC_ImageCache* APIs were introduced. If it were introduced a long time 
ago, I can exclusively use FTC_ImageCache*. Otherwise, I may have to add 
a run-time check.

Thanks,

Jungshik
