<brief_description>
A plugin that advanced tooltip for its handled resource type.
</brief_description>
<description>
Resource tooltip plugins are used by [FileSystemDock] to generate customized tooltips for specific resources. E.g. tooltip for a [Texture2D] displays a bigger preview and the texture's dimensions.
A plugin must be first registered with [method FileSystemDock.add_resource_tooltip_plugin]. When the user hovers a resource in filesystem dock which is handled by the plugin, [method _make_tooltip_for_path] is called to create the tooltip. It works similarly to [method Control._make_custom_tooltip].

<description>
Create and return a tooltip that will be displayed when the user hovers resource under given [param path] in filesystem dock. For best results, use [method make_default_tooltip] as a base.
The [param metadata] dictionary is provided by preview generator (see method EditorResourcePreviewGenerator._generate]).
[b]Note:[/b] It's unadvised to use [method ResourceLoader.load], especially with heavy resources like models or textures, because it will make the editor unresponsive when creating the tooltip. You can use [method request_thumbnail] if you want to display a preview in your tooltip.
