I'm afraid you think quite wrongly here.  The problem is that there's no 
way the core can know whether that call is needed to get a correct 
drawing or not.  The API call's name is "set color", not "change color", 
so it should be obvious that the core is perfectly allowed to set the 
color to the same value as often as it likes.  If a driver has a problem 
with that, it should take care of it itself.  If there are many such 
drivers, let them delegate the work to a shared lower-level function or 
let term.c offer an intermediate layer (along the lines of 
term.c:term_suspend, the only caller of term->suspend).

We almost have such an intermediate function already:  there are rather 
few functions of the core that actually call term->set_color:

color.c:set_color()
color.c:set_rgbcolor()
gadgets.c: apply_pm3dcolor()

I must say I'm rather negatively surprised by you asking this question 
at this time.  How come that you have to ask, days after you rather 
openly blamed hidden3d for this?
