pango 1.30.1 coretext bug

[markau0@…]

pango 1.30.1 has a coretext bug that can cause the errors below.

The current MacPorts pango version seems to be 1.30.1 which probably contains the coretext bug.

pango 1.30.0 doesn't have the coretext bug and is ok.

The bug was introduced with pango 1.30.1 and fixed in a later version

Bug 673497 - corefont fallback not always working

The fallback failed when a "small caps" font was requested. This commit improves the fallback support. When the first fallback, trying Sans with the same style fails, we reset the variant, weight and stretch to default values and try again. With Sans we should always be able to adhere to the requested style.

Last but not least, output a sensible error message if all fallbacks fail instead of simply crashing on a NULL pointer somewhere.

coretext: don't insert item in the hash if it originated from the hash

Oversight in my fallback fix, this resulted in things being wrongly destroyed due to unrefs. Oops.
