Attached patch RenderTrace (obsolete) — Splinter Review
This works well on the desktop but we will need some follow up patches on mobile. I don't think this will handle layers with 3D transforms correctly. It also doesn't get the right offsets for temporary layer managers. Best way to go is to fix this up incrementally. Demo: http://people.mozilla.org/~bgirard/rendertrace.html

Why do we need two? Having the input parameter as a gfxRGBA would make a lot more sense here. Converting that to an HTML format color string should be easy. @@ +85,5 @@ > + > + if (aReset) colorId = 0; > +} > + > +void RenderTraceInvalidateStart(Layer *aLayer, const char *aColor, nsIntRect aRect) { const nsIntRect&, modifying parameters in-place is ew. :) @@ +87,5 @@ > +} > + > +void RenderTraceInvalidateStart(Layer *aLayer, const char *aColor, nsIntRect aRect) { > + gfx3DMatrix trans = GetRootTransform(aLayer); > + aRect.MoveBy((int)trans.ProjectTo2D()[3][0], (int)trans.ProjectTo2D()[3][1]); TransformBounds

The reason I made the color as string is because I give an ID to each layer in the R channel, so the parameters are for the GB channels only. The frontend assumes keys all the information by layer color so they must be unique so we need a different RGB color code for each layer. We will likely want to improve this in the near future.

I forgot to remove color[], I will remove it before landing.

Carrying forward r+ I agree let's improve the layer color in a follow up.
