Hi all,
I made some small enhancements to RasterColorEditor panel (accessible
through *Sextante Raster layer popup menu>Change Raster Layer
properties>Raster Color Editor tab*) to manage Color models for single
banded images.
These are the enhancements:
-  the color editor is activated only for single banded images.
- added some other color ramps.
- optimized color ramps display
- added option to invert the applied color model
- added option to set cell values outside a chosen ramp (min<values>max) to
transparent

The original plugin (RasterColorEditorPlugin.class) is still available
through *Raster>Raster Color Editor* menu. It will be deactivated before
next official OJ real., if everybody agree.

I added also a couple of language codes.

I wrote a minimal help page here:
http://ojwiki.soldin.de/index.php?title=Single_band_raster_layer_symbology_%28Sextante%29
Any comment is welcome.

@Alberto.
I revert a bug that inadvertently was introduced with your previous
modifications: color range was strictly set to raster cell min/max values
even if user could modified min/max values in the fields.
 I came across your Raster Style plugin, which is for shore better than the
one embedded into OJ.  I wonder if you still have the idea to embed it into
OJ. In this case I can give you an help. Please, consider also the last 2
options I added to this plugin (invert color and transparency)

best regards

Giuseppe Aruta
