Here is a example of a alternative for the thead control which seems to be "slow" enough....
You just press plus or minus to add threads one at a time, its all hooked up and working in my test version and "seems" to be fine.
Also, I learned how to add icons as you can see by the copy icon, please let me know if its wrong, I can keep redoing the icons until they are correct if there is a need for that
All the tone mapping controls are hooked up and "working" I plan on posting the diff's and describing the member vars for the current state of things sometime tomorrow night if possible.
Please let me know if this new threading interface is ok, I can attack the spin control at a deeper level and hook some of the mouse down messages also and maybe fix it that way or change it to a combo box np.
