Test failing - CppunitTest_cppcanvas_emfplus

Hey all, 

It appears that we are exporting an EMF+ file to PNG, then we do a check to see what color a 
particular pixel is. 

It *looks* like the actual result should actually be 65280 (0x00FF00 or green), but for some reason 
we are checking if it’s 65024 (0x00FE00 or a slightly lighter shade of green). 

This test is for the bug here:

https://bugs.documentfoundation.org/show_bug.cgi?id=77229

Can anyone shed any light on this? I think the test is wrong, but would like some other eyes on the 
code. Thanks!

Chris Sherlock
