function AddToPainting(BmpX, BmpY: Integer): TRect;


Add extra destination points to a programmatic painting operation.
Result is the area that was painted (in screen coordinates).

Normally, painting operations are performed by the user via miBrushTool, but it can be performed with code using:
1. Set the size and color of the brush
2. Start painting using StartPainting
3. Add extra points to the painting operation using AddToPainting (Optional)
4. Enact the painting changes using EndPainting


// Paint a red line of content from 200 pixels above
ImageEnView1.BrushTool.BrushColor := clRed;
ImageEnView1.BrushTool.StartPainting( 50, 250 ); // Start at 50,250
for i := 51 to 200 do
  ImageEnView1.BrushTool.AddToPainting( i, 250 ); // Add destinations to 200,250
ImageEnView1.BrushTool.EndPainting(); // Enact the changes
