Draws a specified area from a TBitmap image after scaling it to a specified area of the canvas.
DrawBitmap is implemented by the TCanvas descendants to draw a specified rectangle area from a TBitmap image. The drawing is made to a specified rectangle area of the canvas. Before drawing, it scales the source image to the size of destination area.
DrawBitmap does nothing if ABitmap is empty. DrawBitmap does not raise any errors in this case.
