The view to be rendered can be specified in one of the following formats:
- path alias (e.g. "@app/views/site/index");
- absolute path within application (e.g. "//site/index"): the view name starts with double slashes.
The actual view file will be looked for under the [[Application::viewPath|view path]] of the application.
- absolute path within module (e.g. "/site/index"): the view name starts with a single slash.
The actual view file will be looked for under the [[Module::viewPath|view path]] of the currently
active module.
- relative path (e.g. "index"): the actual view file will be looked for under [[viewPath]].
If the view name does not contain a file extension, it will use the default one .php.
