Indirect Draws and Bundles

So far JavaScript has decided how many things to draw and has re-recorded every draw each frame. Indirect calls let the GPU supply the counts, and render bundles let JavaScript record a sequence of draws once and replay it. Together they let a compute shader decide what a frame shows while the CPU does almost nothing.
