Bug 1394284 - add fallback discrete procedure for transform animation. r=boris,hiro According to the spec, if one of the matrices for transform interpolation is non-invertible, the used animation function must fall-back to a discrete animation. However, in the current implementation, we always use an identity matrix as a fallback for the non-invertible matrix. Decompose2DMatrix and Decompose3DMatrix both return a boolean, but we just never use it. So, in this patch, we use the returned boolean from the matrix decomposition as a condition, and do the fallback discrete procedure for the non-invertible matrices case.

# 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.
