[Bf-python] GetRawFromObject no workies? and lil fname func

[Campbell Barton]

Just trying to speed up my obj exporter by sing GetRawFromObject rather 
then transforming each vert and normal by the objects matrix.

It dosent work a bit- no matrix is applied at all, is theis know?


Also, I wrote a small fun for  making names for exporting.

this will turn myfile.blend into myfile.bvh,

newFName('obj') # will make the ext an obj


#==================================================#
# New name based on old with a different extension #
#==================================================#
def newFName(ext):
  return Get('filename')[: -len(Get('filename').split('.', -1)[-1]) ] + ext

...
....
.........

Blender.Window.FileSelector(saveBVH, 'SELECT NEW BVH FILE', newFName('bvh'))
