// A few notes about property set handling
//
// Property sets used in Testcap are of two varieties, those that have
// default values, ranges, and stepping, such as VideoProcAmp and CameraControl,
// and those which don't have defaults and ranges, such as TVTuner and
// Crossbar.
//
// Default values and stepping are established by tables in capprop.h,
// no code is required to implement this other than initally creating the tables.
//
// Many of the property sets require the ability to modify a number
// of input parameters. Since KS doesn't allow this inherently, you'll
// note that some property sets require copying the provided input parameters
// to the ouput parameter list, effectively creating a "read, modify, write"
// capability. For this reason, the input and output parameter lists
// use identical structures.
//
// On an SRB_GET_DEVICE_PROPERTY, read-only input data to the driver is provided as:
// pSrb->CommandData.PropertyInfo
//
// ... while the output data pointer is:
// pSrb->CommandData.PropertyInfo.PropertyInfo
