Updated test program to show the issue

Extended my test program and run a few more tests...

Windows:
> Font gotten: Microsoft Sans Serif
> Got size: got 8
> sz: 405, 16
> Font gotten: Arial
> Got size: got 7
> sz: 389, 16

Linux freetype 2.7
> Font gotten: Arial
> Got size: got 8
> sz: 397, 16
> Font gotten: Arial
> Got size: got 8
> sz: 397, 16

Linux freetype 2.6.5
> Font gotten: Arial
> Got size: got 7
> sz: 389, 16
> Font gotten: Arial
> Got size: got 7
> sz: 389, 16


New freetype seems to render the chars bigger.
GdiGetCharDimensions does cut off decimals:
> (sz.cx / 26 + 1) / 2

For freetype 2.7 this is
> 15.2692307692 --> 15

For freetype 2.6.5 this is
> 14.9615384615 -> 14

When on freetype 2.6.5 Arial is rendered to small. We can't even implement a
rounding for such cases, because if we actually request Arial as font, it needs
to be that way.
When on freetype 2.7 Arial is rendered bigger, what changes the size from what
we expect on windows.. But it works fine in that specific case, where Arial is
substituted...

So we actually have two issues here, Arial being a bad substitution, and
freetype 2.7 leading to Arial being to big.
