   branches/1.0-gt2-2.6/src/schmitzm/geotools/gui/JMapPane.java
Log:
* JMapPane now sets SCALE_COMPUTATION_METHOD_KEY to SCALE_OGC to avoid regular exceptions when not BW parameters are provided.

getRenderer().getRendererHints().put(
	StreamingRenderer.SCALE_COMPUTATION_METHOD_KEY,
	StreamingRenderer.SCALE_OGC);
