class Present

Complete execution of all feed-forward operations.

If executing an operation produces an error (e.g., CreateTransform(0)), an [`OnError`] event

is emitted. Operations that produce errors are ignored and the channel is closed.

If the execution is completed successfully, [`OnNextFrameBegin`] emits NO_ERROR along

with other valid fields.

The client may only call [`Present`] when they have a non-zero number of present credits,

which are tracked by the server. The server may increment the number of credits when it

fires the [`OnNextFrameBegin`] event, which informs the client when it receives additional

present credits. Each [`Present`] call uses one present credit and decrements the server

count by one. If the client calls [`Present`] with no present credits, the server will

return a `NO_PRESENTS_REMAINING` error.

The client should assume that prior to receiving any [`OnNextFrameBegin`] events, they have

one present credit.

Every [`Present`] call results in one [`OnNextFrameBegin`] event, and one

[`OnFramePresented`] event, typically in that order.

When the commands flushed by [`Present`] make it to display, an [`OnFramePresented`] event

is fired. This event includes information pertaining to all [`Present`]s that had content

that were part of that frame.

See [`fuchsia.ui.composition/PresentArgs`] documentation above for more detailed information

on what arguments are passed in and their role.
