Hi,
it is so cool :-). Thanks very much! Can you create simple step by step 
tutorial? I was able to use it, but I didn't do some thinks too good. 
'Texture baker' created some white flecks here, etc.

>   	This is a behind the scene improvement.
>   	Very simple concept: At all time, the listbase for object is always sorted with selected elements as head and unselected as tail.
>   	That enables to cut off pretty much all the loops that dealt on selected or unselected objects only, meaning they only have to loop over parts that interest them.
>   
>   	To do this, a couple of new functions have been added:
>   		selectObject(struct Base *base): Select and object, preserving list order
>   		deselectObject(struct Base *base): Deselect an object, preserving list order
>   		testObjects(void): test if the list has a valid order (accessible through Alt-Shift-O temporarely)
>   		sortObjects(void): Sort the list on load
>   
>   	And a couple of macros in blendef.h to end loops when they should.
>   
>   	WARNING: I had to disable listbase sorting using the depgraph to use this properly. Eventually, the depgraph will be used by itself (Ton said he'd look at it in his two weeks). Using it to sort the base list really give suboptimal results, considering what using the graph directly could do.
>   
>   BoundBox select on object:
>   	Modified selectprojektie to accept buffers of different size, so in object mode, the buffer adapts to the number of objects (no more Buffer Full errors).
>   	Also made the selection loop much smarter and killed a drawing call (for each object in the loop) that made selecting on large scene really crawl.
>   
>   Some quaternion math functions that were missing from arithb.c
>   	That pretty much says it all, not very interesting I guess...
