Layer system problem with shader system or between P2D and P3D

[knupel]

Problem can become from item need to pass something to image,
because when we use image, this one is use to display on the main PGraphics > g

Problem when the PGraphics layer is pass to image and after we use shader system. Not all the part is thread and the other part is flickering... very uggly. To avoid that we pass all the layer is G but by this way the 2D rendering and 3D rendering have conflict sometime, specialy when the we pass the rendering to background... bref il ya un gros problème à gérer.
