Behdad Esfahbod 1245395a60 [coretext] In hb_coretext_font_create() set ptem 
Otherwise setting the CTFont was ineffective as it would have been
recreated anyway unless font size was set to 18 CSS points.

Behdad Esfahbod 493a005d95 [set] In add_sorted_array(), bail if data is not sorted 2017-12-16 11:49:39 -05:00
Behdad Esfahbod a7bd6d7a4c [collect_glyphs] Bail if input data looks like garbage 
Specificaly, when a range or sorted array has unexpected order, we take that as
font data being garbage and bail out.  This fixes significant slowdown on a bad
version of Chandas font which has a 600KB GPOS with garbage inside.

Later on, I like to add a maximum-work counter for collect_glyphs to protect
against malicious fonts as well.

Behdad Esfahbod 87cc5a65cb [collect_glyphs] In PairPosFornat2 do not collect classDef1 
The coverage already covered that.

Behdad Esfahbod 81f27df4d9 More work towards improving collect_glyphs() against bad input 
The three "XXXXX"'s should be switched to false.  Doing that separately for ease
of bisecting...

Behdad Esfahbod 5d02572034 [set] Add add_sorted_array() 
Not optimized to use sortedness yet.  Also start putting in place infra
to faster reject bad data.

A version of Chandas.ttf found on some Chrome bots has 660kb of GPOS,
mostly junk.  That is causing 48 million of set->add() calls in
collect_glyphs(), which is insane.

In the upcoming commits, I'll be speeding that up by optimizing
add_sorted_array(), while also reducing work by rejecting out-of-sort
arrays quickly and propagate the rejection.

There's more to be done, but this shaves off most of the fat.
