You can, instead of using a frame-based approach, repaint as needed. The 
lack of state is in the interface, behind the scenes a library can do 
caching. I don't remember the link, but there was some guy who rewrote 
his traditional gui for a cellphone to an imgui one, and stated that 
performance was about the same.

One benefit though is that in normal gui's, a whole lot a state is 
retained and duplicated between the application and the gui library. In 
complex application, that sucks performance.
