Once upon a time, 413abbe16465a7b49472ac110e42939e853e24a1 added versions of some put_no_rnd_pixels functions for use in VP3 and Theora (with an explicit check so that they are only used for VP3 and Theora). When this was moved to hpeldsp (from dsputil) in 3ced55d51c2e65b37e50d500dff88bcd80e01b9c, the check was replaced by a check for the bitexact flag (and a CONFIG_VP3_DECODER compile-time check), so that these functions were now used for other codecs as well. Later commit 1dfc3cf89d0eb026af28be46294b85d79499ffb5 split off the "VP3-specific bits into a separate file", yet these bits were not really VP3-specific bits at all any more. (The error was repeated in commit 0a39c9ac0bfd7345fe676b4e2707d9cec3cbb553.) This commit has not been reverted, because this would make future changes from Libav (from where it originated) harder, yet Libav is no more, so this commit effectively reverts 1dfc3cf89d0eb026af28be46294b85d79499ffb5.
