#3116 new enhancement

spatial oblogation per layer basis

Description

MapServer is missing capabilities to spatially filter a layer (spatial obligations/restrictions). This is necessary for datasets (vector and raster data sources) where only limited (here: spatial) access is granted to individuals.

The supplied patch uses another layer (similar to an tileindex layer) as spatial obligation. Draft only.

Patch adds a new key RESTRICTION to the layer object which can point to a layer representing the area where access is allowed. Works for raster output only. Data outside the given area is removed from output. Open issues: code clean up, handling of map background color, limiting queries/gerfeatureinfos to the area given in restriction layer.
