Incorrect bounding box for "translations" and "rigid" transformation types

[Marian-Braendle]

Hello again :)

I noticed that the bounding box of objects that have a restricted transformation type ("translations" or "rigid") are sometimes not computed correctly:

• if objects that have "translations" type are rotated
• if objects that have "rigid" type are scaled

Text and references are not affected.

I have created a test file that you can open in Ipe where you can observe the incorrect bounding box in different scenarios: bbox_test.pdf

Maybe as a hint: for my Lasso Selection Tool I "corrected" the transformation matrices for each object: https://github.com/Marian-Braendle/ipe-lassotool/blob/90e3eae9ce98856aff49a416fcc3dd07fefcc04e/lassotool.lua#L224

This has been broken since the very beginning of Ipe 7, thank you for getting me to finally confront this.

Fixed in 7.2.29.

And also thanks for your two nice ipelets!
