Description Simon Fraser (smfr) 2018-10-12 15:57:10 PDT

It would be great if the canvas debugging stuff showed how much memory was being used by WebGL (e.g. listing resources like textures and their sizes).

This would be good to debug things like bug 190518.

For 2D it shows the memory use in the Canvas Detail Sidebar. So we have the concept of memory use. We may just need to provide good values for 3D contexts.

Both 2D and 3D contexts show the memory usage of the _context_, but not any associated objects (e.g. textures, buffers, etc).  2D doesn't really have a concept of an "associated object", so there was nothing to show.
