For a long time, we've masked out complex-script codepoints from the cmap on OS X if a font lacks the layout tables (AAT, OpenType or Graphite) required for correct layout behavior. Bug 992100 extends this behavior to Android/B2G (the gfxFT2Fonts backend), to avoid using bad fonts on some Samsung devices.

As per bug 992100 comment 53, we should probably extend this to all platforms, so that we have consistent behavior - in particular, this will affect whether webfonts that lack proper layout tables get used for Indic (etc) characters.

I think this is certainly NOT what we want to do for webfonts...
