screens: `drag` with draggable True moves with the pointer (the place is kept while the screen is shown); `at icon["at"]` picks a transform that Python code stored in a dict (transform names now evaluate to a reference); PreviewSlowText and Move(...) exist as values. Python: Matrix([16 numbers]) for matrixcolor, renpy.has_live2d() is false, renpy.fetch fails like a missing network (games catch it), cache.get_total_size and the texture helpers are no-ops.
