Update 5/8: Added transparency, and it apparently slows down rendering a lot. Update 4/4: Added benchmarking for three variants: axis-aligned (red), two-side interpolation (green), and one-side interpolation (blue). Click Start Benchmarking to have the program graph performance for comparison. Press space to cycle between methods. Thanks to @TheLogFather for the original scripts. I replaced his version of @Jamohyperturbopro's fast tri fill script with my custom-made triangular integration filler. It is based off of @DCPU-16's scanline triangle. The major advantage of this method is a fix for off-screen rendering. However, it comes at the cost of some speed for backend processing. Speed can be increased by cutting down on the number of scanlines by increasing resolution.
