If you are using git, you can run
git am <<the patch filename>>
or - if it fails - try
git am -3 <<the patch filename>>

Non-gitters will just remove some lines from the top of the patch file to get pure diff

I assume you have run the unit tests, and they all pass. Please comment. Thanks.

However, you are right template_renderer_factory needs a bit more work. In get_renderer, the $searchpaths array needs to

$path = $rootpath . '/' . $module;
if (!is_null($subtype)) { $path .= '/' . $subtype; }
if (is_dir($path)) { $searchpaths[] = $path; }

Is probably a good way to do it.

Anyway, template renderer is only an experimental proof-of-concept. No need to be too concerned with it now.

p.s. I like the typo. Maybe we can start using "Fix a lot" instead "Thanks a lot" and so on
