Nader, curious whether there's any update on the ability to retarget canvases. I'd love to have this ability for shared element. :)

Hey Nader, is there anything we can do to help ship a first experimental version of this API? We are starting a quite big rearchitecture of the SystemUI container codebase (see

Hey Jordan thanks for reaching out, we are in the middle of stabilizing the Android U release, afterwards this feature request is a #1 priority. I don't think there is a feasible workaround in the meantime.

Add support for DrawScope canvas retargeting
Relnote: "Updated DrawScope api to introduce
the ability to retarget rendering into a different
canvas with alternative density/layoutdirection and
size.
Updated DrawContext to support configuration of
density and layout direction as well as making
the canvas configurable."

Description
We need to introduce the ability to retarget a given DrawScope to render into a separate canvas. This is useful in situations where we want to create a "GhostView" in some circumstances (ex. drag and drop) as well as shared element transitions that require drawing the composition hierarchy at a specific instance then redrawing it.
Additionally this would allow us to introduce some post processing on the RenderNode to either draw the same content several times more efficiently with a rasterization layer or as input to other visual effects (ex. blur).
