big work
what was reliable before is now not, in recent versions of renpy, which is why we added that new config (which I put in say.rpy, but it can be moved somewhere else)
Also fixes the game_menu's title position, incidentally
some changes are incompatible with my diary and achievement branches, respectively, they will need to be merged with a bit of manual care
use the dedicated xycenter property
avoid setting the previous end-interpolation values before starting the new one, to avoid a jump if the player advances too quickly (also shortens the code)
add subpixel True, even though it doesn't seem very effective
prepare improvement in next renpy version
