Different glyph outputs for Windows and Linux

[Hubert Liberacki]

Hello,

The project in which I am working is using FreeType for generating glyphs. We 
are cross-platform focusing on both Windows and Linux OSes. We found out that 
using our product on different os generates visually different outputs. We have 
the same FreeType version on both Windows and Linux.

My question is whether it's correct behavior or we are using the somehow 
incorrect configuration of FreeType? If this is correct behavior, then is this 
even possible to unify the output across all-platform using FreeType?

Kind regards,
Hubert Liberacki
