Apologies if this has been discussed before. I’d like to create the
appearance of motion blur by drawing multiple Cairo shapes at opacity of
1.0 / [number of motion blur samples]. In openGL or After Effects I would
set the blending to alpha add so that the final result retains its original
opacity. Is this possible in Cairo? I couldn’t find an equivalent
compositing operator. Keen to hear any workarounds or suggestions.
