segfault in QuadMesh with Numeric

Starting from CVS mpl, I tested examples/quadmesh_demo.py and found that it worked only with numarray; Numeric and numpy refused to cast the Float64 X and Y arrays to Float32. So I fixed that in CVS by using the astype method. Now the demo works with numpy and numarray, but segfaults with Numeric. I have not tried to track the problem down; it is very low priority for me. Given the momentum towards numpy, it might not be worth tracking down at all.

System is Linux;
>>> Numeric.__version__
'24.0b2'
