[CSS Shaders] Cached validated programs are destroyed and recreated when there is only one custom filter animating https://bugs.webkit.org/show_bug.cgi?id=96563 Patch by Max Vujovic <email@example.com> on 2012-09-12 Reviewed by Dean Jackson. Before this patch, in FilterEffectRenderer::build, we would first clear the old effects and then create the new effects. Suppose we have one FECustomFilter animating on the page. This FECustomFilter holds the last reference to the cached validated program. Before this patch, we would first destroy the old FECustomFilter, which would destroy its cached validated program. Then, we would create the new FECustomFilter and have to recreate the validated program. This patch makes FilterEffectRenderer::build keep the old effects around until we're done creating the new effects. This way, we won't recreate validated programs. No new tests. We can't test this because the validated program cache is not exposed to web pages. * rendering/FilterEffectRenderer.cpp: (WebCore::FilterEffectRenderer::build): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@128387 268f45cc-cd09-0410-ab3c-d52691b4dbfc
