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.
