From 0fbbdb37c87b5824729f65c7fbac05223024fd27 Mon Sep 17 00:00:00 2001 From: Adam Jackson Date: Wed, 22 Oct 2014 13:19:18 -0400 Subject: [PATCH] composite: Wrap GetSpans GetSpans should flush composition from children to parent, just like GetImage and SourceValidate. Fortunately no one is likely to have noticed, since to hit this you're already deep into failure town.
