change lerp

the previous lerp implementation could cause in certain scenarios that if t = 1, the output would be different than the input. Because of floating point precision, `a - (b - a)` wasn't guaranteed to return `b`. Down the line, when using trim paths for example, this small difference could cause the path not to draw properly. Changing it to this implementation solves the issue. Diffs= 1be3488d52 change lerp (#9000)
