 * NV-CONTROL Protocol Version History
 *
 * 1.0 - 1.5   NVIDIA Internal development versions
 * 1.6         Initial public version
 * 1.7         Added QueryBinaryData request
 * 1.8         Added TargetTypes
 * 1.9         Added QueryTargetCount request
 * 1.10        Fixed target type/id byte ordering for compatibility with
 *             pre-1.8 NV-CONTROL clients
 * 1.11        NVIDIA Internal development version
 * 1.12        Added StringOperation request
 * 1.13        NVIDIA Internal development version
 * 1.14        Fixed an NV_CTRL_BINARY_DATA_MODELINES double scan modeline
 *             reporting bug (vsyncstart, vsyncend, and vtotal were incorrectly
 *             doubled)
 * 1.15        Added AVAILABILITY_TARGET_ATTRIBUTE_CHANGED_EVENT
 * 1.16        Added TARGET_STRING_ATTRIBUTE_CHANGED_EVENT
 * 1.17        Added TARGET_BINARY_ATTRIBUTE_CHANGED_EVENT
 * 1.18        Updated QueryTargetCount to return a count of 0, rather than
 *             BadMatch, if an unknown TargetType is specified
