I have converted the rasterizer to use fixed point, will post a more elaborate status report once I get SIMD working with fixed point, but here are the highlights:
1. Fixed point calculation is notably faster.
2. I have analysed fontdue, and it doesn't seem to have any significant difference in the rasterizer algorithm, just some minor improvements which I am in the process of porting over.
3. Added comments and cleaned up the code a bit. More documentation work in progress.
4. I am also testing the renderer on a variety of fonts and have found some issues, (specifically when the outlines overflow the glyph width).
Will post more testing details and perf numbers in a report soon.
Regards
Anurag
