        <pre>Hi,

The OrientationView Widget of rock does not follow the standard rock 
coordinate frame. (x pointing forward, y pointing left and z pointing 
up) and the right-handed positive rotation.
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/Cartesian_coordinate_system#In_three_dimensions">http://en.wikipedia.org/wiki/Cartesian_coordinate_system#In_three_dimensions</a>

For example, if we have a negative pitch angle (along Y-axis) following 
right-handle positive rotation the widget should depict the pitch up 
w.r.t a level position (because is negative) and right now the 
representation is down.

Could someone verify this and tell us where is this representation made?

Thanks,

Javier.
