ICC complains like so:
harfbuzz-gpos.c(95): warning #592: variable "error" is used before its value is set
return error;
^
However, line 95 is never executed because the condition on line 94 is
always false. That's why it's a false positive. The same construct
happens in the other two places.
Still, silence the warning.

We need to do ACCESS_Frame for each 2 byte frame, otherwise
the position of the cursor in the input stream will not be
updated by enough, and we will read twice as many pairsets.
Depending on the value read for the SecondGlyph in the
broken pairsets, we might get strange kerning results.

This is pretty much the same fix as in
be0dfa34737a014e7ad060a90c4c24be9998fe13 but for PairPos
format 1 instead of 2.
With very simple GPOS tables we would waste a lot of memory on
caching an uncompressed table, so we now compress it in memory
as well.

just empty
Considering a subtable to be invalid when it was empty meant that it
returned an error causing all further hinting to be aborted. This means
that we get no hinting in certain cases with certain fonts.

Sometimes GPOS tables are used for kerning and can grow quite
large if the font is unoptimized. In that case, allocating the
maximum size for each ValueRecord will have a great impact on
memory consumption. For GPOS tables which do not contain device
tables, we only allocate the memory actually need to store the
data instead.
While it would be possible to optimize memory for GPOS tables that
contain device tables as well, this is not a part of this patch.
