Update raster query code to support shapes beyond simple polygons...

[sdlime]

As part of some consulting work I had to add support (in trunk) to handle points, lines and polygons in msQueryByShape(). Works nicely. However, I didn't update the raster code, just not familiar enough with it. So, we either need to make sure to throw an error with rasters and unsupported shape types or add the necessary support.

It's nice with clients like OpenLayers being able to generate adhoc geometries to handle more cases.

I see the core changes Steve made are in r9613 - I will try to match those for raster. The core raster shape query is the test:

            if( rlinfo->searchshape != NULL
                && msIntersectPointPolygon( &sPixelLocation, 
                                            rlinfo->searchshape ) == MS_FALSE )
                continue;

This will need to be extended to support three different types of search shapes. The targets are always points.

I have implemented support for point and line raster query in trunk (r9646). I also implemented a modest test of this with a line in msautotest/mspython/rqtest.py (r9645).

I have only done modest testing.
