[Libreoffice] [REVIEW 3-5, 3-5-0] fdo#42543: Empty wizard page in reportdesign

Hi,

https://bugs.freedesktop.org/show_bug.cgi?id=42543

When you use the report designer, at some stage you get to a page (step
2) which is blank; but when you click there, you can edit the data.

The problem is that commit

http://cgit.freedesktop.org/libreoffice/core/commit/?id=efc6b840a0423099d6c3e0d33c14d34637fbba4c

changed the order of painting of the overlapped controls; in this case,
a background image is painted over the Edit fields; but the clicks go
through, so in the end they are shown when you click there.

As a fix, I propose this:

http://cgit.freedesktop.org/libreoffice/core/commit/?id=03e17a141fbb4e1242de9d9979b5b699e6840454

Just get rid of the background image; in my opinion, it even looks
better without that, and is the least intrusive change.

Can you please review for -3-5 and -3-5-0?

Thank you,
Kendy
