I cleaned up the code a bit and used `ftbench` to get performance numbers for the `smooth` and `dense` rasterizers.
There is much room for improvement in the ported code, as can be clearly seen in the performance graph.
Regarding my work on the documentation, I am working on a markdown file that explains the implementation of the smooth rasterizer.
I am collecting all the queries I have regarding the implementation and will post them here soon.

Subject: Font-rs GSoC Phase 1 update
Hello Werner and other folks,
Here is the status update on the font-rs port for FreeType:
1. Code:
I have pushed the ported font-rs code to the "gsoc-anurag-2022" branch (here: https://gitlab.freedesktop.org/freetype/freetype/-/tree/gsoc-anurag-2022)
The rasterizer is working now (albeit with some artefacts, image attached), but the code is in a very early stage and I'm working on cleaning it.
It took me longer than I had hoped to get it working, but there should be regular updates from now on.
2. Documentation:
I have started work on improving the existing documentation (explanations for functions, macros, algorithms), but I feel my understanding of the smooth rasterizer is still lacking.
I have been reading up on the _algorithm_, but I still have some trouble with understanding the _implementation_ in FreeType.
I would really appreciate it if I could get any pointers or resources regarding that, maybe old mailing list discussions or such.
I hope to have a draft of the documentation improvements by next week.
3. Performance Comparison:
I am working on cleaning up the code and should have numbers to show soon.
TL;DR:
1. Initial Ported code is in the "gsoc-anurag-2022" branch
2. Documentation is under progress (would appreciate help regarding this)
3. Initial Performance comparisons coming soon.
Regards
Anurag
