[I proposed:]
float fl_reset_scale(); / void fl_restore_scale(float s);
[Manolo wrote:]
What about
fl_undo_scale() / fl_redo_scale()
or
fl_scale_undo() / fl_scale_redo()
[Ian wrote:]
I quite fancy:
fl_override_scale() paired with fl_restore_scale()
Just to add extra confusion to the discussion.

Throwing my hat in the ring:
fl_unscale() / fl_rescale()
..or if there's a stack:
fl_push_scale() / fl_pop_scale()
The latter would be my favorite *if* we had a stack, in analogy to
fl_push_clip() and fl_pop_clip() which appears related - and indeed it
is somehow because you can't change scaling w/o taking care of clipping.
So this would be (with types and parameters):
float fl_push_scale(float s); / void fl_pop_scale();
The former would return the previous scale value (or void would also be
OK). The latter *could* return the /new/ scale value but void would be fine.
Unless we go the push/pop route with stack I'd favor Ian's
fl_override_scale() or my proposal fl_reset_scale().
Or, what about this?
float fl_set_scale(float s); // returns old value
void fl_restore_scale(float s); // as we have now
