Qunxin Liu 7cb002cb58 [subset] bug fix in prune_langsys 
we should not cache visited langsys cause 2 different Record<Langsys>
could have different Tag while pointing to the same Langsys, a langsys
is redundant in Record<Langsys> A does not mean it's redundant in Record
B. Same thing for visited_script.
Also adding the number of features in the LangSys's feature list to the
visited langsys count so it's more accurate.
Plus some improvement in langsys compare()

Matthias Clasen e7ab42b246 [layout] Fix handling of baseline variations 
For BASE table format 1.1, the handling of design

values.
