Subject:  Addition to non-delegation list:
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=refs%2Fheads%2Fmab%2Ffast_vtkviewSmesh;p=modules%2Fgui.git

 Addition to non-delegation list:
Add all 3d quadratic, biquadratic and
triquadratic elements to the list  of
elements  which  have  to  be handled
natively.
