Hi,
if I render a text using pango_ft2_render_layout() on a bitmap using
ft_pixel_mode_grays, is the output in linear space or gamma-corrected?
Whatever FreeType assumes. Pango doesn't set anything, so the question is
what's the FreeType default gamma. Donno. Perhaps ask on FreeType list?

The bitmap in question is used as a GL_ALPHA texture later on, so I need
pixel coverage values.
