Detailed Description

Querying driver properties.

All drivers will respond to requests for driver properties.

If a driver implements a configuration option as a driver property, then the driver property is available to get and set while the driver is running. Driver properties are a solution to static configuration file options which force the Player server to be stopped before a driver's configuration can be changed.

Driver properties are implemented as four basic types: IntProp, DoubleProp, StringProp, and BoolProp.
