Tip for debugging CppunitTest_sd_tiledrendering failure

[Khaled Hosny]

I’m having a failure on Linux in this test, I can reproduce it locally
but I have no idea how to debug it:
http://ci.libreoffice.org/job/lo_gerrit/2956/Config=linux_gcc_release_64/console

(for https://gerrit.libreoffice.org/#/c/31053/).

The test apparently checks if a mouse event at a certain position does
something, and since I’m changing how line spacing is calculated it
might have caused some vertical shift. But I don’t understand the code
of the test that much and don’t know where to start, any tips?
