Packaged files demonstrating problem

This bug was originally posted to the FreeType project bug report ( https://savannah.nongnu.org/bugs/?33288 )

Attached is a test application (main.cpp) that demonstrates the problem. 

It tries to render a "2". But the middle curve is reversed when using: FT_LOAD_TARGET_NORMAL, FT_RENDER_MODE_NORMAL
 
See attached text file: freetest.txt (unix line feeds )
freetest_crlf.txt (win32 line feeds )

[tested with DejaVuSans 2.32] 

I'm quite sure this is a bug in the font itself. 

If you debug glyph `two' with different xres and yres, you can see many artefacts. For example, at (x-ppem,y-ppem) = (50,44), the diagonal stroke gets distorted to the right, and at (54,44), the spike to the left is eight times larger than at (55,44), which is what your original settings are equivalent.
 
I've attached images which demonstrate it.

I've slightly changed the hinting of "2" to fix this (even though I'm never keen to change these important glyphs in fear of breaking something bad).

You can test it by compiling the font in SVN or by waiting for the next snapshot at https://bugs.freedesktop.org/show_bug.cgi?id=37395
