Transparancy issue - glitch "line" #18

Closed JaCzekanski closed 5 years ago

When drawing two triangles which have one edge in common transparency issue apprears: 2018-06-08_02h25_56

Mostly visible on fading screens (Crash1 startup screen). Probably bug in rasterizer algorithm.

Subpixel precision (1bit more should do) will resolve this issue.

Fill rule had to be implemented to prevent double writes to the same pixel - it finally resolved these transparency glitches. Fixed in 55621f3d3a251c2c56a0dc419e40222e3799b33b
