Description
Creates and initializes a TCanvas from a parent window.
The AParent parameter is the parent of the TCanvas.
The AWidth and AHeight parameters specify the Width and Height of the TCanvas, respectively.
Note: Do not directly call a TCanvas constructor. Call it using the TCanvasManager class.
MyCanvas := TCanvasManager.CreateFromWindow (AParent, AWidth, AHeight);
