[poppler] [PATCH] Annotations appearance stream regeneration

[Carlos Garcia Campos]

When a property of an annotation changes we need to invalidate the
appearance stream so that next time it's drawn, it's
regenerated. There's a method for that, but it's called only by the qt
frontends, and sometimes unnecessarily (called when the property change
doesn't affect the appearance of the annotation, for example).

Attached patches should fix this problem by moving the invalidation
handling to the core (which also fixes the annots appearance stream
regeneration in the glib frontend for free).

Could Fabio or someone else check that this works for qt?

Thanks!
