[Biojava-dev] TranslatedSequencePanel / LabelledSequenceRenderer fix

[Michael Kowalchuk]

Hi,

I'm developing a J2SE application using BioJava 1.4, and I've found a
bug where a LabelledSequenceRenderer will not be drawn correctly on a
TranslatedSequencePanel.  Specifically, the label will not be visible at
all, and the graphics will be cut off on the left.

I've fixed this by translating the Graphics2D context by the minimum
leading space specified by the renderer.  This is equivalent to what is
done in SequencePanel.

There is still a placement problem with LabelledSequenceRenderer when
the TranslatedSequencePanel is vertically aligned, but it works
perfectly when aligned horizontally.  I'm unsure if this is the fault of
TranslatedSequencePanel or LabelledSequenceRenderer.

I've attached my patch and the source code for a demonstration of this
bug to this message.
