		TR_DNA	x1_dna,
		TR_DNA	x2_dna,
		double	width,

	)			[virtual]

Paints the visual appearance of a feature.

Parameters:

	p	the QPainter to paint to
	x_pix	the pixel coordinate of the upper left corner of the rectangle where the feature should be painted
	y_pix	the pixel coordinate of the upper left corner of the rectangle where the feature should be painted
	x1_dna	the left most position that should be painted given as a dna coordinate relative the left side of the read.
	x2_dna	the right most position that should be painted given as a dna coordinate relative the left side of the read.

Implements FeatureGui.
