Canvas.PersistentBeginSized
Persistent begin sized through the Canvas runtime.
Built into Yeho; no package import is needed. Native services require an admitted host and the correct resource lifecycle.
Canvas.PersistentBeginSized(int red, int green, int blue, bool full_redraw, int expected_width, int expected_height) -> boolStatus: registered-intrinsic
Parameters
int red- Supply red as int.
int green- Supply green as int.
int blue- Supply blue as int.
bool full_redraw- Supply full redraw as bool.
int expected_width- Supply expected width as int.
int expected_height- Supply expected height as int.
Call Canvas.PersistentBeginSized
A complete typed caller with illustrative arguments. Native operations need the corresponding host and resources.

Notes and source
The example checks the call shape. Opening windows, recording audio, changing files, network operations, and process operations have real effects when run. Follow the corresponding package lifecycle before using live resources.
