That's an interesting suggestion. Alan and I have been deciding on what
is going into the M5 release (M4 will be out in a week or two) and it is
going to be mainly performance oriented stuff - including some
reasonably major restructuring of the way the loader works to make it
potentially-possible to work with scenegraph I/O in a limited subset of
cases. We could attack this issue at the same time.
Our thoughts on the API are that we would include an extra method in the
loader interface setCapabilityMap(Map capBits, Map freqBits). The map
would use the class as the key and an int[] as the value for the bits to
be set. ie
int[] bits = (int[])capBits.get(Appearance.class);
if(bits != null) {
for(int i = 0; i < cap_bits.length; i++)
myLoaderAppearance.setCapability(bits[i]);
}
