Don't include the clip bbox when calculating bbox for some LPEs

Michael Terryrequested to merge
mikix/inkscape:lpe-deformation into master

Fixes #5617

I need some help understanding this. Basically, I didn't address the odd "it only changes after I move it / paste into the doc" behavior. But rather, I stopped the clip mask bbox from affecting the LPE calculations. Which feels right to me?

I only changed two LPEs, and wanted feedback on this approach before I adjusted more. When would you ever want the clip bbox to affect the LPE bbox? (genuine question, this isn't my area of expertise)

This flag was introduced in commit 95b1c7b5. @jabiertxof - do you remember that change? Is it important to include the clip mask bbox as part of the LPE bbox?
