Increments the views_ui_contextual_links_suppress() static variable.
When this function is added to the #pre_render of an element, and 'views_ui_contextual_links_suppress_pop' is added to the #post_render of the same element, then all contextual links within the element and its descendants are suppressed from being rendered. This is used, for example, during a View preview, when it is not desired for nodes in the Views result to have contextual links.
views_ui_contextual_links_suppress_pop()
function views_ui_contextual_links_suppress_push() {
views_ui_contextual_links_suppress((int) views_ui_contextual_links_suppress() + 1);
}
