Just my mind wandering about the possible 'tesselation' block 
(which is a bad idea, IMNSHO, at least with my current code).
Order in blob is irrelevant, whereas order of transformation is important,
even if the rotate/scale/translate can all be summarized in one single
matrix, but for transformation of mesh there is no possible summarisation, and
order is still important.

I should probably not have mentionned the blob.
