[Freetype] Error in ftxgpos.c / ftxopen.c

[Dave Williss]

I've found an error in ftxgpos.c in the pre1.4 version

 

On line 278, it does...

 

    new_offset += base_offset

 

However, base_offset is the base offset to the GPOS

table and it's trying to lookup a gdef table here.  So

it should be

 

    new_offset += gdef->offset

 

Another change I would suggest....

 

In ftxopen, instead of returning TTO_Err_Invalid_SubTable

and failing, have it just skip that subtable.  I hit this one

using the font mangal.ttf.  In Load_ClassDef2() it hit one

that was really wacko.  I could send the font if you don't

have it (it's about 138K).
