-- HOW TO REPORT A BUG

  If you think you have found a bug in qx11Grab, we would like to hear about it so that we can fix it. 
  Report Bugs to : https://github.com/HJCMS/qx11grab/issues

  Always include the following information in your bug report: the name
  and version number of your compiler; the name and version number of
  your operating system; the version of qx11Grab you are using, and what
  configure options it was compiled with.

  If the problem you are reporting is only visible at run-time, try to
  create a small test program that shows the problem when run. Often,
  such a program can be created with some minor changes to one of the many
  example programs in qx11Grab's examples directory, or to the autotests that
  are available in the public source repository on https://github.com/HJCMS/.
