Calculation of normals for Irregular shapes in primitives and draw primitives is unreliable.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use Arial.
2. Make a Textfield3D.
3. Use a ShadingColorMaterial.

What is the expected output? What do you see instead?
Good shading. Bad shading.

Please use labels and text to provide additional information.
Many font glyphs contain redundant points in its description forming a 0
area triangle and hence affecting (a) the normal of the primitive irregular
shape and (b) its descendent as a draw triangle.

Hello. I´m currently working on an project using TextField3D in combination 
with ShadingColorMaterial. it´s really crucial for me to get this combination 
working. Are 
there any bugfixes in progress? It would be great if I could get access to the 
sourcecode and contribute to solve the problem. Thank you...
