High-Low offset for GDI+

For GDI+ render candle stick's High-Low is always offset one pixel to the left. Visible best for narrow sticks (offset.png). GDI render if free of this issue.

Actually it's other way round. Shadows are placed correctly, bodies are offset.

Fixed.
The candle width is decremented one pixel when using the GDI+ canvas.
This aligns better the high-low line in the middle of the candle.

Attached a test project to verify several options that might affect the display aspect. (candle border, candle size, thin high-low line, GDI+ vs GDI canvas, etc)
