The patch here hoists pseudo-element handling onto ThreadSafeLayoutElement. I have another patch which hoists stuff from TNode to TElement, but want to make sure this patch passes try first.

Corresponding Gecko bugs, where @Manishearth has given r+s:

* https://bugzilla.mozilla.org/show_bug.cgi?id=1310463
(Sorry for the large structs_{debug,release}.rs changes; I thought it was too much trouble to disentangle the useless changes from the legitimate ones.)
Holding off on landing this until the Gecko patches are reviewed and landed.

webgl: Add basic support for framebuffer attachments
This is by no means a complete implementation, but I've slowed down on working on it, so I think we should look at what it takes to merge the current code. There are some major features missing, like initializing renderbuffers to 0 (uninitialized memory leak), tracking the attachments' attributes (width/height/format) for parameter requests, and lots of missing glCheckFramebufferStatus() validation. On the other hand, this is enough to run some demos using FBOs.

Instead of maintaining a dummy restyle damage field for text nodes, we can just
perform the necessary parent inheritance and is_changed adjustments on the fly
in ThreadSafeLayoutNode, simplifying the requirements on the style system.

This patch introduces a "legalizer", which encapsulates all the
anonymous flow generation logic in one place. The legalizer knows how
to, for example, place adjacent blocks with `display: table-cell` in the
same table row.
Improves etsy.com.
Closes#13782.
