I did a quick sanity check by just using the fblin4.c code to
make sure that I could see some freetype output when using
the new code. The effect is the same as before: no output from
freetype.
I suspect it's something other than the blitter. I put in some
more debugging probes, and see that no matter what size I set
for the font, I always get back the same font metrics. For example,
I have set sizes of 10, 12, 16, and 20 and always get back the
same info:
maxwidth = 11
height = 13
baseline = 11
descent = 101058054
maxascent = 101058054
maxdescent = 101058054
linespacing = 101058054
firstchar =
lastchar = ΓΏ
fixed = FALSE
"Test1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ": width=269, height=13, base=11
The descent, etc info looks fishy. Anyway, I guess there is some
problem in realizing the font.
