Enum UiPass 

pub enum UiPass {
    World,
    Hud,
}

Which of the two screen-space passes a command is painted in.

Everything in this layer used to be painted after post-processing, straight onto the finished frame. That is right for a HUD, which has to stay sharp, and wrong for everything else: a game that draws its figures, rooms and effects as clouds of screen-space particles was getting no bloom, no tonemap, no halation and no grade on any of them. The whole picture went to the screen raw, and the only things the post-processing ever touched were a few background glyphs in the 3D scene.

So there are two passes now. World is painted into the HDR scene buffer before post-processing, in the same space as the 3D scene, and everything downstream (bloom, light shafts, flare, tonemap, grade, grain) applies to it. Hud is painted after, straight to the screen, and stays crisp.

By default particle clouds and filled rectangles go to World, since a filled rectangle is what a game lays down as the ground under its matter and it has to stay under it; text, outlines, bars and sprites go to Hud. A panel is split: its fill goes to World and its border to Hud. UiLayer::begin_world, UiLayer::begin_hud and UiLayer::end_pass override all of that for a run of commands.

Variants

World

Into the scene buffer, before post-processing. Blooms, grades, shakes.

Hud

Onto the finished frame, after post-processing. Sharp and stable.
