Lay groundwork for adaptive resolution system (#1395)

* Make transform node accept footprint as input and pass it along to its input

use f32 instead of f64 and add default to document node definition

* Add cull node

* Fix types for Transform and Cull Nodes

* Add render config struct

* Add Render Node skeleton

* Add Render Node to node_registry

* Make types macro use macro hygiene

* Place Render Node as output

* Start making DownresNode footprint aware

* Correctly calculate footprint in Transform Node

* Add cropping and resizing to downres node

* Fix Output node declaration

* Fix image transform

* Fix Vector Data rendering

* Add concept of ImageRenderMode

* Take base image size into account when calculating the final image size

* Supply viewport transform to the node graph

* Start adapting document graph to resolution agnosticism

* Make document node short circuting not shift the input index

* Apply clippy lints
