[Freetype] Strange behavior

[henry . maddocks]

I ve got an issue with char size in my freetype to opengl library that 
is unrelated to freetype but when trying to resolve it, it has highlited 
some unusual behavior.

Size in openGL is a bit of an abstract concept. For polygons and 
outlines, what's too small for one may be too big for another.

Initially I tried using the point size to scale the glyphs. This was 
fine until I tried very small sizes eg. 2 point. At first the glyph 
outline was a real mess which it turned out to be the grid fitting (fair 
enough) so I change the FT_Load_Glyph function to use non hinted mode 
(FT_LOAD_NO_HINTING | FT_LOAD_NO_BITMAP).

This fixed the glyphs but broke the kerning. The glyphs overlapped or 
even advanced backwards. I changed the kerning mode to be 
ft_kerning_unfitted but that hasn't helped.

This isn't going to effect my lib because I've decided scale is a client 
issue but someone is likely to try and use small point sizes and it will 
look like a bug in my lib.

Is this a bug in freetype or should I be loading/ kerning the glyphs 
differently?
