Tiling LPE: scaling option is misleading

Following issue #3922

Option "Scale %" gives the user the illusion that scaling will be relative (%) but it is not.

Steps to reproduce:

• open Inkscape
• draw a square of a given size
• apply tiling LPE,
  • 1 row, 4 columns,
  • scale -25%, left to right option.
  • Path > Object to path
  • Path > break apart
  • with select tool, look at W and H of each square

What happened?

Absolute size decreasing is constant from a square to another = 0.25 x size of first square.

What should have happened?

Absolute size decreasing should not be constant because:

• second square side = 0.75 x first square size as expected.
• third square side should be 0.75 x second square side = 0.75² x first square size
• fourth square side should be 0.75 x third square side = = 0.75^3 x first square size

-25% should not be calculated once but from each new square !!! That is the purpose of relative (%) options !

Inkscape Version and Operating System:

• Inkscape 1.3-dev (d40a2dcd, 2022-11-16) win 11
