Create an own, custom preview generator.
Check if the resource changed, if so, it will be invalidated and the corresponding signal emitted.
Queue the resource being edited for preview. Once the preview is ready, the receiver's receiver_func will be called. The receiver_func must take the following four arguments: String path, Texture preview, Texture thumbnail_preview, Variant userdata. userdata can be anything, and will be returned when receiver_func is called. Note: If it was not possible to create the preview the receiver_func will still be called, but the preview will be null.
Queue a resource file located at path for preview. Once the preview is ready, the receiver's receiver_func will be called. The receiver_func must take the following four arguments: String path, Texture preview, Texture thumbnail_preview, Variant userdata. userdata can be anything, and will be returned when receiver_func is called. Note: If it was not possible to create the preview the receiver_func will still be called, but the preview will be null.
