Transparent Mode Modifier

• pen, line, rectangle, filled rectangle, ellipse, filled ellipse, polyline, polygon, text
  
  If transparent mode is enabled, drawing with a the semi-transparent brush will cause color mixing. This is a regular drawing mode.
  
  If transparent mode is disabled, drawing with a semi-transparent brush will replace the destination color and alpha values (just like drawing with transparent color). For example, if you draw the blue circle with the semitransparent brush, you'll get just semi-transparent blue circle - independently of source image.
