setSpatialRequest - motion to add respect for scale hints for spatial request

[astrid_emde]

• at the moment the spatial request is triggered when a layer is visible and conected to a wfs_conf and is queryable

It would be a nice enhancement if we would respect minscale and maxscale of a layer.

A WFS request would only be triggered if the layer is visible and the scale is in-between minscale and maxscale.

We could provide a new variable in wfs_conf_filename:

• var respectScaleHint = true;

The code would look like this:

if(o.gui_layer_wfs_featuretype != '' && o.gui_layer_visible == '1' && o.gui_layer_minscale <= mb_getScale(mod_wfs_spatialRequest_target) && o.gui_layer_maxscale >= mb_getScale(mod_wfs_spatialRequest_target)){
...

What do you think?
