Garret Rieger 38a9628885 [subset] simplify handling of table subsetting depedencies.
Allow the dependency checker to see all tables that will be subset. Use this to fix the HMTX/VMTX dep check against glyf. Don't delay hmtx/vmtx subsetting if no glyf table is present.

Garret Rieger 0853e5d9d7 [subset] if table dependencies can't be resolved fail the subset.
Avoids getting stuck in an infinite loop.

Garret Rieger 2c0afde737 [subset] add an inprogress accelerator to plan.
