 .B UseHardwareJPEG
 Use hardware-accelerated JPEG compressor for video if available.
-\fBx0vncserver\fP can detect video areas on the screen and handle them
-separately from the rest of the screen, for better performance.  If the
-client supports Tight encoding and JPEG compression, such video areas will be
-sent as JPEG-encoded rectangles.  And if this option is on, compression will
-be hardware-accelerated (currently, supported only in SGI/IRIX equipped with
-appropriate hardware).  Default is on.
