Bug#1111366: wxhexeditor: hex panel not scrolling when using wayland

[Adam Chyła]

Package: wxhexeditor
Version: 0.24+repack-2+b4
Severity: important
Tags: patch

Dear maintainer,

after opening a file, the hex panel does not update while moving over the file
content when using a wayland compositor. This makes the app unusable
in this setup.

The workaround is to run the wxHexEditor with x11 backend instead of wayland,
like this:

$ GDK_BACKEND=x11 wxHexEditor

The bug has already been reported 
(https://github.com/EUA/wxHexEditor/issues/143)
and fixed by the upstream with the git commit
01aa3aa460814a5bac74c14fa2894a4703c8e7b6, available at
https://github.com/EUA/wxHexEditor/commit/01aa3aa460814a5bac74c14fa2894a4703c8e7b6

Here is the patch that fixes the issue and applies cleanly
on the wxhexeditor_0.24+repack-2.debian:
