/*!
A GPU based renderer for the web.

It serves as an experimental render backend for [Servo](https://servo.org/),
but it can also be used as such in a standalone application.

# External dependencies
WebRender currently depends on [FreeType](https://www.freetype.org/)

# Api Structure
The main entry point to WebRender is the `webrender::renderer::Renderer`.

By calling `Renderer::new(...)` you get a `Renderer`, as well as a `RenderApiSender`.
Your `Renderer` is responsible to render the previously processed frames onto the screen.

By calling `yourRenderApiSender.create_api()`, you'll get a `RenderApi` instance,
which is responsible for managing resources and documents. A worker thread is used internally
to untie the workload from the application thread and therefore be able to make better use of
multicore systems.

## Frame

What is referred to as a `frame`, is the current geometry on the screen.
A new Frame is created by calling [`set_display_list()`][newframe] on the `RenderApi`.
When the geometry is processed, the application will be informed via a `RenderNotifier`,
a callback which you employ with [set_render_notifier][notifier] on the `Renderer`
More information about [stacking contexts][stacking_contexts].

`set_display_list()` also needs to be supplied with `BuiltDisplayList`s.
These are obtained by finalizing a `DisplayListBuilder`. These are used to draw your geometry.
But it doesn't only contain trivial geometry, it can also store another StackingContext, as
they're nestable.
