commit 35cc68814a9537c31fde146e171e7b0bbdfe211e
Author: Andreas Huber <andih@google.com>
Date:   Mon Aug 16 08:48:42 2010 -0700

    Only enable support for yuv to yuv conversion on passion, where it's available, use the slower yuv->rgb565 path everywhere else.

commit d8ac5a8814103e60d11d2acf61997fc31a1dc58d
Author: Andreas Huber <andih@google.com>
Date:   Fri Aug 13 13:56:44 2010 -0700

    The software renderer takes over all rendering, converting from yuv to yuv if possible and rgb565 otherwise.

commit 684972074b74318bdcb826ed9b5b0864d2d2e273

    A first shot at supporting the new rendering APIs.
