technically not as correct, but works all the same and is relatively faster (but it will be replaced with better actions in the future anyway)
the pickle lock, if any, for removing them in the future, becomes easier to solve
turn the show into a call screen
replace all return actions with specific local actions (WIP, more changes to come)
make the global variables at least dynamic
make the mode parameter a parameter of the label (so, a dynamic variable too, as a result)
replace the bigger actions with local labels
tweak text entries, comparisons, iterations... details
in addition to benigh simplification, this actually fixes a bug : setting pos and align in the same line is a bug, it's always been unspecified, you should have been setting *anchor* instead. xycenter does that now.
I chose not to add them directly in the screen, to keep it readable
but even though they're still global variables, now they are dynamic and cleaned as soon as we exit the menu
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
It is used in a txt draft which I didn't change, it can be done if deemed necessary
I think this function should be kept off, as it is both more dangerous and slower than the workarounds
