When using grid with normal perspective adjustment and with inverse transformation behaviour is the same. With moving of corners whole grid is transformed.

This is right behaviour for inverse tranformation because user tries to adjust grid to fit to future image. But when doing normal correction user tries to make lines in image vertical and horizontal. Then unmoved grid - with horizontal and vertical lines - is helpful tool.

To shortly summarize:

- with normal transformation grid should stay in place
- with inverse transformation grid should move
