I fixed this, and also tested my fix with the ROI sample application. Now ROI's
can also drawn around near the edges of a map (and also overlapping the map rim).

Is it okay if I change this in CVS head Paul/Julien?

I changed the following 2 things:

1) cwc_roi.js

in CWCROIManager_Pix2Geo(x, y)

    //if (x >= 0 && x <= width &&
    //    y >= 0 && y <= height)
    if (x >= 0 && y >= 0)

removed the check that x and y have to be inside of the map. The result of this
function is also valid outside of the map, the extrapolation is valid outside of
the map.

2) ROIRenderer.php

function Geo2Pix:

Removed the following lines:
        //if ($nGeoPos < $dfGeoMin)
        //    $nGeoPos = $dfGeoMin;
        //if ($nGeoPos > $dfGeoMax)
        //    $nGeoPos = $dfGeoMax;
