[GTK][WPE] SkiaCompositingLayer: incorrect z-ordering at Snow Stack
https://bugs.webkit.org/show_bug.cgi?id=314883
Reviewed by Nikolas Zimmermann.
Make SkiaCompositingLayer3DRenderingContext::Layer public and make
SkiaCompositingLayer3DRenderingContext::paint() receive a list of
SkiaCompositingLayer3DRenderingContext::Layer instead. This way while
collecting the 3D context layers we can build the
SkiaCompositingLayer3DRenderingContext::Layer without having to iterate
the layers again in paint(). The geometry for 3D context is now computed
taking into account the flattened bounding box when needed instead of
always using the layer rectangle, which is what actually fixes the
incorrect z-ordering.
