Expand description

Render all scanlines from the rasterizer using a span generator.

This is the generic rendering function that supports gradients, patterns, and other per-pixel color effects. For each scanline span, the span generator produces an array of colors which are blended into the output.

Port of C++ render_scanlines_aa() (span generator variant).
