Performs the basic processing associated with a widget action (using a generic Gtk widget as the target)

True if this step is empty (eg, due to being just after a finished action)

Deserializes some edits and runs them on the animation. The edit string can be generated by the diagnostics command line tool.

Transforms a 2D point using this transformation

Retrieves the frame model for this animation

Retrieves the model for the drawing tools for this animation

Clears all layers from this renderer

Read and deserializes a set of edits from the edit log

Restores this saved state into a drawing

Transforms a coordinate via the transformations specified in these properties

Reads a squished float from a source stream

Writes a usize

Sends an event immediately to an event sink

Writes a u64 that's expected to have a small value

Applies all of the properties for the specified element (including those added by attached elements)

Returns the x, y position of this control point

Retrieves the sprite transform set for the state

Retrieves the paths for this element, if there are any

Writes a time to the target

Retrieves a reference to the state in this context

Sends a single request that produces a single response to the storage layer

If this control has subcomponents, finds them

Retrieves the IDs and types of the elements attached to the element with a particular ID (Element data can be retrieved via element_with_id)

Reads a usize from this source

Tests that a layer has the same content before and and after undoing another edit

Creates a new DOM node with the specified child nodes appended

Ensures that an element ID has an assigned value

Reads a u64 (in the format where it's expected to have a small value) from this source

Sets the data associated with a particular type and widget

If possible, combines two transformations into one

Generates a serialized version of this edit on the specified data target

Retrieves the canvas cache at the specified time

Returns the responses for a stream of commands

Causes the canvas to be invalidated

Returns true if this is a control point (vs a point on the curve)

Writes this element to a data target

Encodes a byte array to this target

Adds a new effect to this effect description

Draws this rectangle on a graphics context

Retrieves the view ID for an object

Writes a string value to this target

Retrieves a sink that can be used to send events to any attached streams

Retrieve or create a property ID in the database

Converts a NSString name into a rust string

Retrieves the sprite that rendering has been redirected to

Converts this path to a list of subpaths

Updates a one or more elements via an update function

Adds a set of reversed edits to the start of this list of edits

Attempts to load the keyframe for the specified element for editing

Writes a time to the target

Sends an event to the events object

Sets the properties for a property target

Stores a particular drawing in the cache

Performs an action when the bindings of this object change Note: call this *before* reading any of the object properties to avoid issues with missed

Creates a copy of this object with a different actions

Creates a control with an added controller

Clears a canvas and sets it up for rendering

Sets the clipping area to the current path

Returns the list of edits that were committed to the animation

Reserves a path for a new file (this path is valid and won't be re-used by future calls but no files will exist here yet)
