Bug 1260324. Don't draw garbage to the screen if an image doesn't happen to be decoded. r=seth Layout has been using imgIContainer::IsOpaque to determine if the image will draw opaquely to all pixels it covers, and doing culling based on this. However imgIContainer::IsOpaque doesn't guarantee anything. It only describes if the image, when in a decoded state, has all opaque pixels. So if the image doesn't have fully decoded frames around (because they got discarded) it may not draw opaquely to all of its pixels. So we create a new function that first checks if there is a fully decoded frame.

# Welcome to the new world of configure. We're working on moving to a
# python based configure. In the meanwhile, remains of the old autoconf
# based configure is in old-configure.in.
# If you need to add something, please come talk to the build system
# peers for now.
#
# Because adding a configure file in the tree is going to conflict with
# existing configure files in people's (and automation) work trees, and
# because some automation jobs are still running autoconf and configure
# "manually", this file is actually an m4 file that is processed by
# autoconf, but doesn't call any autoconf macros. The `divert` line
# below ensures the script that follows is output by autoconf.
