[Devel] patch cffgload.c

[Dirck Blaskey]

Hello FreeTypists...

Here is a small patch to cffgload.
I've got a an embedded cff font subset in a pdf file that was bombing in the
hinter because glyph->points is null.  My guess is there is a bug in the font,
probably some kind of spurious endchar signal, but I honestly don't know.
This patch keeps from going down into that code in this case -
the bomb goes away, and the glyph renders ok.

I can provide the font fragment if anyone is interested.
