Renderer before/after render...

This definitely makes sense - have you looked into whether there's any extra cost for doing this like there was for reactivity in #17 ? I'm happy to do so in the next couple days if not!

Well, while doing the typescript refactoring I was thinking may be it's better to add :

• addListener(type: 'init' | 'mounted' | 'beforerender' | 'afterrender' | 'resize', callback)
• removeListener(type: 'init' | 'mounted' | 'beforerender' | 'afterrender' | 'resize', callback)

Renderer event api with 0.3.0-beta.0 :

• onInit(cb: InitCallbackType): void

• onMounted(cb: MountedCallbackType): void

• onBeforeRender(cb: RenderCallbackType): void

• offBeforeRender(cb: RenderCallbackType): void

• onAfterRender(cb: RenderCallbackType): void

• offAfterRender(cb: RenderCallbackType): void

• onResize(cb: ResizeCallbackType): void

• offResize(cb: ResizeCallbackType): void

• addListener(t: T, cb: EventCallbackMap[T]): void

• removeListener(t: T, cb: EventCallbackMap[T]): void

Example :

this.$refs.renderer.onBeforeRender(() => {})

And we can use a prop to get renderer when it's ready :

• onReady: Function as PropType<(r: RendererInterface) => void>

But I don't know if we need more events props.
