Revert because of regressions. Sorry, this didn't appear the last times I ran
the tests. -I found out that the files were missing on one of my computers.- I
don't know what happened. The files are there. Maybe I had done too much
editing back and forth or on different project files.
The regression is about transparency groups in a rotated page.

> The rendering of the transparency groups works only if the whole page is
> rendered. If you try to render only a part of the page where is a
> transparency group placed, you will get only the white image or an image with
> shifted pixels representing applied soft mask. The simple fix is attached in
> the patch, including the test and the resources used for testing.
