#- size and correction size functions for packages.
-#- invCorrectSize corrects size in the range 0 to 3Gb approximately, so
-#- it should not be used outside these levels.
-#- but since it is an inverted parabolic curve starting above 0, we can
-#- get a solution where X=Y at approximately 9.3Gb. we use this point as
-#- a limit to change the approximation to use a linear one.
-#- for information above this point, we have the corrected size below the
-#- original size wich is absurd, this point is named D below.
