[ft] Incorrect y position glyph render

[Edward Lam]

Hi,

I'm rendering the text using freetype 2.7 and Adobe's free Source Code Pro [1] 
font but I can't seem to figure out how to render out the glyphs correctly 
vertically since it seems that the demo program ftstring also has the same 
problem. The sample text I'm rendering is '1+4*8' and the '*' character in 
ftstring isn't being rendered higher than the '+' like it should (eg. on Windows 
using WordPad). This results in it being hard to tell the difference between the 
plus and multiply operators. Any ideas?

Thanks,
-Edward
