Attempt to recover valid format 3 FDSelect data from broken CFF fonts (bug 1146106)
...
According to the CFF specification, see http://partners.adobe.com/public/developer/en/font/5176.CFF.pdf#G3.46884 , for `format 3` FDSelect data: "The first range must have a ‘first’ GID of 0".
Since the PDF file (attached in the bug) violates that part of the specification, this patch tries to recover valid FDSelect data to prevent OTS from rejecting the font.

Prevent adding invalid values in CFFDict_setByKey (bug 1068432)
...
In the font in question, there are a couple of `topDict` entries that have invalid values (`0xF 0xF`, i.e. just eof markers without any actual numbers).
This causes the `parseFloatOperand` function, inside `CFFParser_parseDict`, to return `NaN`. Currently we pass this broken font onto the browser, which OTS unsurprisingly rejects.
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1068432 .
