[Openev-discuss] Layer Cleanup

[Frank W. <war...@ho...>]

Folks, 

I have applied a bunch of patches so that as raster layers are removed from
views, the underlying GvRaster's are properly destroyed, and their references
on the GvManager are properly removed.  If there are no remaining GvRaster's
references a GDALDataset that is open, the dataset will be closed.  

This will be important for Ahmed's work removing old raster layers, and opening
new ones - for instance. 

BTW, you can set the environment variable CPL_DEBUG to ON, in order to see
debug messages about when GDAL files are opened, and closed, and the 
destruction of major objects (like GvRaster, GvRasterLayer and GvViewArea). 
This can be helpful to check that destruction is happening as it should.

PS. The ``recent file list'' is also now in the file menu. 

Best regards,
