[GSUB] Don't set new lig_id on mark ligatures If two marks form a ligature, retain their previous lig_id, such that the mark ligature can attach to ligature components... Fixes https://bugzilla.gnome.org/show_bug.cgi?id=676343 In fact, I noticed that we should not let ligatures form between glyphs coming from different components of a previous ligature. For example, if the sequence is: LAM,SHADDA,LAM,FATHA,HEH, the LAM,LAM,HEH form a ligature, putting SHADDA and FATHA next to eachother. However, it would be wrong to ligate them. Uniscribe has this bug also.
