jfkthame 19e77e01bc [shape-plan] Don't look for a cached plan if variation coords are specified. Fixes #549. (#550)
This is a temporary hack just to avoid incorrect shaping results, pending proper support
for caching shape-plans with variation coordinates.

Sascha Brawer 01c3a88543 Fix "Since:" tags

Resolves #103

Behdad Esfahbod eb0bf3ae66 Relax inert checks
Previously, when creating an object from inert inputs (eg:
"hb_font_create(hb_face_get_empty())") we returned the inert
empty object.  This is not helpful as there are legitimate
usecases to do that.

We now never return the inert object unless allocation failed.

Tests are revised to reflect.

Behdad Esfahbod 30eed75de2 [shape-plan] Fix typo!
The only effect is, if shaper_list was not NULL and no shaper was found,
we now don't insert anything into cache and return earlier.

Since our types are not associated with their methods, marking
constructors makes them inaccessible from bindings.  Undo for now.
