Unittest fail because of 125% screen resolution on Windows 10

Hi all,

if I set my PC to 100% screen resolution, the unit tests work. If I set 
my PC to 125%, unit tests fail. 125% results in 120dpi, that is below 
the threshold for scaling.

The failing tests are
in CppunitTest_sw_ooxmlexport4 the test
testFDO74215::Import_Export_Import
with
Expected: width:11.25pt;height:11.25pt
Actual  : width:9pt;height:9pt

and
in CppunitTest_sc_subsequent_filters_test the test
ScFiltersTest::testOptimalHeightReset
with
Expected less or equal than: 8
Actual  : 9

There might fail other tests too, I have not investigated further.

Does a parameter exists for make check to exclude single tests?

Kind regards
Regina
