[away3d] BumpMapGenerator avaible!?

[martin]

hello,
is in away3d a bumpmpgenerator avaible? i want to create a normalmap
with appling a bump on runtime.
generating a normalmap from my source image is no problem, but i want
to use the applybump-method from the normalmapgenerator class and the
bumpsource should come from the original image with an generator or
other function.
thx
martin
