It should be reasonably quick with shorter lines as well; the performance target was lines of 30-50 pixels in length.
There is about 400 cycles of setup, before the routine enters any loops.
It uses DDA for the stepping and has pregenerated code segments that render 16 pixels at a time; the last modulo-16 segment is rendered with loop iteration and conditional logic for each pixel.
(The last modulo-16 segment can be sped up by pregenerating more code segments, but I didn't think it was worth the implementation time & extra memory cost when I wrote the routine.)
