You get less blurrier output if you don't do subpixel position of
glyphs.
How do I control whether or not subpixel positioning of the glyphs occurs?
What is the translation component of the transform? If it is non-zero then the
grid fitting won't help against blurriness (since the pixel-aligned
outline will then
be shifted to between pixels, making the rendering all blurry).

In tracing into the call to FT_Render_Glyph, it eventually goes into
ft_smooth_render_generic.
When it gets here origin is NULL and so FT_Outline_Translate is not
called. So I think the answer to your question is that no translation
is occurring.
FreeTypeGL is rendering a single glyph using FT_Render_Glyph and then
using the resultant gray-scale bitmap to create a 2D GL texture.
I noticed while tracing through ft_smooth_render_generic that
FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not defined.
