references for algorithm

[mdsumner]

I thought it worth collating any related references for this method, both for the need for a link for CRAN, and for general usage. I'd write this into a vignette or the readme if you prefer.

This paper, seems to fit the bill as a suitable peer-reviewed ref:

http://www2.tku.edu.tw/~tkjse/2-4/2-4-1.pdf

Good details on scan-line behaviours at horizontals, shared vertices:
http://www.cs.mun.ca/av/old/teaching/cg/notes/raster_poly.pdf

Course on rasterization, in PPT format:
https://www.cs.virginia.edu/~asb/teaching/cs445-fall06/slides/09-rasterization.ppt

"Conservative and Tiled Rasterization Using a Modified Triangle Setup" - possibly related to discussion at #1 (comment)
https://users.aalto.fi/~ailat1/publications/am2005jgt_paper.pdf

Another lecture Polygon Scan Conversion and Z-Buffering:

Good refs to have! Especially because we'll want to use some of them for line and point rasterization eventually. Here are notes that I referenced in that past: https://dl.dropbox.com/s/q4o4f0rab0iiyqt/polyfill.zip . The professor had taken them down but emailed them to me.

I'll close this now that we have Wylie (1967) in the description and docs.
