Processing bug?

@neilcsmith

Also for a gui library where you might wan’t to draw on a different PGraphics instead of the main one.

add_solver(
    $("slider", "thumb"),
     (e, r) -> {
            g.fill(colors[0]);
            g.noStroke();
            g.rect(r.x, r.y, r.w, r.h);
    }
    , DRAW
);  

And about the preprocessor.
I would much more prefer that it get’s replaced by a dumber thing.
We would have to get rid of color as a primitive but I can live with that.
How difficult can it be, just explain we have millions of colors, each color has a number…

The when compiling paste a bunch required to make it working on top and at the bottom.
Maybe don’t allow for sketches without any function anymore. It was a nice and clean thing, but in practise hardly used.
