[udig-devel] jgrass related tools

Hi Jody, John, following the emails I saw the need for some screenshots.
I am afraid I can just send them in right ow with some description.
Here they are:

Active Region: it is the region on which processing is limited.
Through that you make sure that even if you have a map of resolution
1x1 meter and size of 60000x60000 (which would kill your machine if
running analyses on it) it gets downsized and resampled to the needed
resolution and size (set in the active region).

See: active_region_graphic.png

Raster legend: it gives the possibility to make color ramps on single
banded rasters.

See: jgrass_raster_legend.png

Vector legend: Not sure what that on as more than the usual legend.
Perhaps just the nicer frame. I think there was some more to it. We
can also thik to remove it perhaps.

See: jgrass_vector_legend.png

Then there is anoter one: Raster Color Mask
This makes a single color of a coverage transparent.
For example see: color_mask.png where I set the color to white on the
visible map in the background (you do not see the elevation map)
and: color_mask_2.png where the transparency is applied.

Note that the last one is not SLD, since that was all but performant.
So I opted for a coded way and keeping memory in the preferences.

Thanks for your work,
Adrea
