<div class="markdown level1 summary"><p>Loads all themes from an assembly, and registeres them for use by theme controllers
in the current application.</p>
<p>
This method scans all resources in the specified assembly, and selects
those with names ending in ".c1theme" (case insensitive).
If a theme cannot be loaded (e.g. due to a duplicate name or other error),
it is skipped (i.e. no exception is thrown).
