* Sets options for a display, inheriting from the defaults when possible.

* that the options inherit from the default display whenever possible. This
* avoids setting too many options as overrides, which will be harder for the
* user to modify later. For example, if $this->setDefaultOptions() was
* previously called on a page display and then this function is called on a
* block display, and if the user entered the same title for both displays in
* the views wizard, then the view will wind up with the title stored as the
* default (with the page and block both inheriting from it).
*
* @param array $options
* An array whose keys are the name of each option and whose values are the
* desired values to set.
* @param \Drupal\views\View\plugin\display\DisplayPluginBase $display
* The display handler which the options will be applied to. The default
* display will actually be assigned the options (and this display will
* inherit them) when possible.
* @param \Drupal\views\View\plugin\display\DisplayPluginBase $default_display
* The default display handler, which will store the options when possible.
