Visual quality regressions about fontdue

[mooman219]

A test font I used showed no diff with the new atan2, but my test font is kinda bad. I'll swap to libm's correct atan2 since this doesn't impact performance, all these slower math bits are part of the precomputation on font creation and not the raster pipeline. Thanks for catching this.

Can you give it a try with Sun's atan function (what libm uses)? I assume for fonts with not enough curves, the inaccuracy actually looks bad. The fonts I test with all are wall over done with geometry (Like roboto). Here's the commit: f0054b6

Yup, that seems to have done the trick !
The rendered characters look exactly like before !
Thanks for the swift modification, I'll close this now.

Awesome, I'll publish 0.1.1 today eventually
