Hi,

When you have a surface or orbital and you change the isovalue for  
example, this will not make a new quicklist to render. There several  
ways we could solve this:

- Make surfaces into a primitive. GLWidgetPrivate::updateCache will be  
set to true of we add, delete or update surface points or triangles.  
This would also allow surface points to be selected etc… (I think  
this is the right way to implement it, we allready have the surface  
primitive type… Just want to check what other people have to say  
before I start writing code because I can fix it really fast using the  
second method)

- Add a function to GLWidget to set updateCache to true when engines  
emit Changed.

If we make a surface primitive do we store color in it? If we do we  
can renderQuick ESP, … colored surfaces and update() can be called  
when you change the color. Otherwise renderQuick just has to use one  
color. Or is switching color to slow in renderQuick?

Never mind, I see that Marcus already solved it.
