Derelict Assimp RemoveComponent

[Lemonfiend]

This might be OT, or missing in Derelict's Assimp bindings, I'm 
not sure.

The aiPostProcessSteps.RemoveComponent flag signals that I want 
Assimp to skip importing certain components.
But where/how do I specify these?

The docs only mention 
http://assimp.sourceforge.net/lib_html/config_8h.html#afc0a4c00fb90c345eb38fe3f7d7c8637
which is less than helpful..

uint flags = aiPostProcessSteps.GenNormals;
flags |= aiPostProcessSteps.RemoveComponent;
// And now for the components?

auto scene = aiImportFile(path, flags);

Any ideas?
