I recently added code for optimizing rendering to the current clip. If
you get a recent biojava (preferably source-code - try cvs or the
nightly builds), then you will see some new-in-1.4 code in the
.gui.sequence package. Take a look at SymbolSequenceREnderer, arround
line #117 for how to get the minimally visible range.
