Image: parallel rendering and window overwriting
Created by: robbycerantola
- Draw an image by splitting it in half and render the two halves using parallel threads thanks to rayon::join.
- image() wrapper decide wich rendering function to use based on images size. Smaller images infact render slower using parallel implementation because of inerent overhead.
- Very fast non transparent method to render full window (or stripes of it).
- Update image benchmark
