From 7994dba6c0f20f47a990a09e05a71bd73df74c69 Mon Sep 17 00:00:00 2001 From: Johann Date: Wed, 26 Oct 2016 21:24:46 -0700 Subject: [PATCH] partial_idct_test: add _add_ test The result of the transform is added to the destination buffers. In the existing tests the destination buffer is always empty so that portion of the code was never exercised.
