CPC mode 5 : replaced the global Constraint_mode by a state (Image_mode) in each versioned T_Page: This allows keeping it sane when swapping to Spare, and when Undo/Redoing. Also fixed the first page when program starts, it was unnecessarily allocating pointers for the maximum number of layers(16)/frames(999)
