Hiding static components

There is a HIDDEN axis priority that behaves like the STATIC priority but does not show in the Machine Tool Position dialog. For example:

<machine_part>
  <axis>
    <control_info ADDRESS="T" HOME="0" VALUE="0" PRIORITY="HIDDEN" />
    <simple_rotary X="0" Y="2550" Z="0" I="0" J="0" K="1" />
  </axis>
</machine_part>
