Tests for improvement in rendering

[Regina Henschel]

Hi Tomaž,

I have put my tests to gerrit https://gerrit.libreoffice.org/c/core/+/125013

The test, where the light number is missing is testSurfaceMattePPT.

BTW, I have not yet changed your example 'testFontWorks'. I have read 
your answer too late.

Kind regards,
Regina
