Behdad Esfahbod 1b7994cb3a [aat] Support feature ranges
The hard way...

A bit uglier than I liked it to be, but is proper at least.

Behdad Esfahbod 24a4d397ba [aat] Allow disable feature ranges
Fixes https://github.com/harfbuzz/harfbuzz/issues/4020

This is a hack.

To implement this properly we need to treat runs with different features
as independent runs for running the state machine, as the subtable flags
might be different. That would be a significant change to our internal
implementation.

Behdad Esfahbod d045de78c1 [paint] Optimize PAINT_COMPOSITE
At the start of each paint call the current group is clear.
So we don't need to start a new group for the backdrop paint.

A paint composite really needs one group push, not two.

Qunxin Liu 1eb5445e75 [subset] Fix issue in hb_subset_input_override_name_table()
If a nameRecord with provided name_id/platform_id/encoding_id/lang_id
is not retained after subsetting, create it and insert it to
the name table. So we need to check against retained name_records
rather than name_record in the original name table.
