I was just updating the patch. Basically:
patch 11
delta computation moved from red_current_add_qxl to red_add_drawable (new function from red_current_add_qxl split).
patch 12
computation moved from red_add_drawable to __new_shadow
patch 13
computation moved from shadow_new (renamed from __new_shadow) to red_current_add_with_shadow (called by red_add_drawable)
So patch 13 does two thing, move code and move the computation from a function to another. Also the move move a piece of code just added in the previous patch to another.
My current change just leave code movement in patch 13 making it easier. So I have currently
patch 11 split red_current_add_qxl
patch 12 move delta computation from red_add_drawable to red_current_add_with_shadow
patch 13 move the 2 functions
(basically I changed patch 12 and 13)
